Replace the A20 kernel config with a generic ALLWINNER kernel config that

Add SMP support for the Allwinner A31 and A31s. This updated the existing
code for the A20 to use the new PLATFORM_SMP interface, and extends it to
add support for the new SoCs allowing for both to coexist within the same
kernel.

Almost all copies of platform_mp_init_secondary just called

Remove platform_mp_probe as it's almost identical on most ARM SoCs, and
slightly wrong on the others. We should just check if mp_ncpus is set to
more than one CPU as we may wish to run on a single core even when SMP is
available.

Move ARM_L2_PIPT option to std.armv6 for all armv6 platforms.
Only L2 PIPT cache is supported for __ARM_ARCH >= 6.

In fact, this is just a pure proclamation as this option is used
only in armv4 specific files now.

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.

* Use EARLY_DRIVER_MODULE to attach at the right time

ARM: Use new ARMv6 naming conventions for cache and TLB functions
in all but ARMv4 specific files.
Expand ARMv6 compatibility stubs in cpu-v4.h. Use physical address
in L2 cache functions if ARM_L2_PIPT is defined.

[intrng] Migrate the intrng code from sys/arm/arm to sys/kern/subr_intr.c.

The ci20 port (by kan@) is going to reuse almost all of the intrng code
since the SoC in question looks suspiciously like someone took an ARM
SoC design and replaced the ARM core with a MIPS core.

* migrate out the code;
* rename ARM_ -> INTR_;
* rename arm_ -> intr_;
* move the interrupt flush routine from intr.c / intrng.c into
arm/machdep_intr.c - removing the code duplication and removing
the ARM specific bits from here.

Thanks to the Star Wars: The Force Awakens premiere line for allowing
me a couple hours of quiet time to finish the universe builds.

Tested:

* make universe

TODO:

* The structure definitions in subr_intr.c still includes machine/intr.h
which requires one duplicates all of the intrng definitions in
the platform code (which kan has done, and I think we don't have to.)

Instead I should break out the generic things (function declarations,
common intr structures, etc) into a separate header.

* Kan has requested I make the PIC based IPI stuff optional.

Makeoption ARM_LITLE_ENDIAN does nothing. Remove it since it isn't
consistently used. It was a carry over from NetBSD that FreeBSD
doesn't use.

Stop setting {KERN,}PHYSADDR on armv6, it's unneeded.

Rename arm_init_secondary_ic() -> arm_pic_init_secondary(). The latter is
the name the function will have when the new ARM_INTRNG code is integrated,
and doing this rename first will make it easier to toggle the new interrupt
handling code on/off with a config option for debugging.

Add the A20 glue code for if_dwc.

This code initializes the GMAC clock and sets the pin mux to rgmii.

It also override the if_dwc defaults to set the alternate descriptor type
and MII clock used on A20.

Tested on cubieboard2 and banana pi.

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.

Make a comment reflect reality.

Move the items common to all SoCs to a single file.

Include vm/pmap.h for pmap_kextract.

Stop using machine/fdt.h in the arm kernel code when we don't need it.

Build the cpufunc_asm_* files based on the cpu type, not which config file
we happen to be building.

Remove cpufunc_asm_arm11.S from the ARMv7 configs, it's not used.

Stop building unused cpuvunc_* files, we don't need anything from these.

Rename bus_space-v6.c to bus_space_base.c, because it's not v6-specific
and now some v5 Marvell systems are using it. Only define fdt_bus_tag
if option FDT is defined.

Rename gic_init_secondary to arm_init_secondary_ic to help with the merge
of the arm_intrng project branch.

Remove -Wa,-march=armv7a from arm kernel configs, it makes clang 3.5 sad
and apparently isn't needed now that we're using the integrated assembler.

Add -march=armv7a to the kernel compile for all ARM systems which are v7a.

Eliminate irq_dispatch.S. Move the data items it contained into arm/intr.c
and the functionality it provided into arm/exception.S. Rename the main

also update its signature to reflect what has long been reality: it is
passed just a trapframe pointer, no interrupt number argument.

Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352. Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.

Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.

Remove STARTUP_PAGETABLE_ADDR from the ARM configs and replace it with
memory at the end of the kernel.
