Add a MULTIDELAY option to allow the ARM kernel to have multiple DELAY

Move the Allwinner kernels to use fdt_pinctrl. This will read the pin
configuration from the FDT data, then set the pins into the requested
state. As part of this the gpio controller now reports the correct number
of pins instead of returning the number of bank * 32.

To allow for a future consolidated kernel we add the SOC_ALLWINNER_A10 and
SOC_ALLWINNER_A20 kernel options. These need to be set as appropriate for
the SoC the kernel will boot on.

Remove compatibility shims for legacy ATA device names.

We got new ATA stack in FreeBSD 8.x, switched to it at 9.x, completely
removed old stack at 10.x, so at 11.x it is time to remove compat shims.

Enable if_dwc for Allwinner A20 based boards.

This enables the gigabit ethernet on cubieboard2 and banana pi.

A special thanks to Netgate who gently provided me with a banana pi almost

Add the LED definitions from vendor's DTS.

Add gpioled support to A20 kernel.

While here rename the gpio phandle to match the one used in the vendor's
DTS.

In preparation to support other A20 based boards, rename the CUBIEBOARD2
kernel configuration to A20.

There are other boards (namely the banana pi) that use exactly the same
devices.

Additionally, we are moving from static FDT support (DTB compiled
in-kernel) to DTB passed to kernel by the boot loader (ubldr). The u-boot
for these boards are already available on ports and as the crochet support
for these boards isn't committed yet, this should not bring any issues.

Add AHCI attachment code for Allwinner A10/A20 SoCs.

The Allwinner SoC has an AHCI device on its internal main bus rather
than the PCI bus. This SoC is somewhat underdocumented, and its SATA
controller is no exception. The methods to support this chip were
harvested from the Linux Allwinner SDK, and then constants invented to
describe what's going on based on low-level constants contained in the
SATA standard and guess work.

This SoC requires a specific AHCI channel setup in order to start the
operations on the channel properly.

Clock setup and AHCI channel setup idea came from NetBSD.

Tested on Cubieboard 2 and Banana pi (and attachment on Cubieboard by
Pratik Singhal).

Ensure that all arm kernel configs contain ALT_BREAK_TO_DEBUGGER and not
BREAK_TO_DEBUGGER if they have a serial console (most do). A burst of
serial line noise (such as unplugging a usb serial adapter) can look like
a break and drop a working system into the debugger. The alt break sequence
(<CR>~^B) works fine on both serial and non-serial consoles.

Add the MMC/SD driver for Allwinner SoCs.

This is based on the patch sent by Alexander Fedorov with the following
fixes/improvements:

- Better error handling;
- Clock is derived from PLL6 (obtained from netbsd);
- No more unnecessary busy loops on interrupt handler;
- style(9) fixes and code cleanup.

I also want to thanks Martin Galvan who has sent an alternative
implementation with some interesting fixes.

Tested on CubieBoard2, Banana-Pi (thanks to netgate!) and Cubieboard1
(Pratik Singhal).

This is intended to pave the way for the upcoming GSoC work (and make
easier the build of images for the supported boards).

Remove unnecessary devices from allwinner kernels.

Add the gic to files.arm under "device gic" and use it with the
CUBIEBOARD2 config. This is common across a few SoCs so should be a common
option.

Clean up the ARM kernel configs to use 'include<space><tab>"file"'.

Move the first batch of common armv6 options to std.armv6.

Create std.arm and std.armv6 config files and include the right one from
each of the existing kernel configs. This gives a place to put config
that applies to the entire arch.

Add the ARM_NEW_PMAP option to std.armv6. This is working well in early
testing and it's time for wide exposure, but it's still nice to be able
to fall back to the old implementation for testing when a problem comes
along. Eventually the option and the old implementation will go away.

The opportunity now exists to move a whole lot of boilerplate from all the
arm kernel config files into std.arm*, but that's a commit for another day.

Build and install the DTB for all the supported AllWinner SoCs.

We will need them when we start booting using ubldr.

Remove MODULES_OVERRIDE="" and WITHOUT_MODULES="ahc" from armv6 configs.

These are left over from long ago when there was no way to load modules
on early armv6 platforms, and when there was a build problem with ahc
that has long since been fixed, and they just keep getting copy-pasted
into new configs.

Remove "New" label from NFSCL/NFSD now that they are the only NFS
client/server. While here, remove duplicate NFSCL from sys/conf/NOTES.

Add option USB_HOST_ALIGN=64 for all SoCs that have 64 byte cache lines.

Revert r260440. I didn't realize that most of this change was already
in effect due to r250753. That is sufficient for all SoCs with a 32 byte
cache line size. Systems with 64 byte cache lines will need the option;
that will be done in a separate commit.

Thanks to loos@ for pointing out r250753.

Add option USB_HOST_ALIGN to configs that contain 'device usb'. Setting
this to the cache line size is required to avoid data corruption on armv4
and armv5, and improves performance on armv6, in both cases by avoiding
partial cacheline flushes for USB IO.

All these configs already exist in 10-stable. A few that don't (and
thus can't be MFC'd yet) will be committed separately.
