arm: Fix duplicate ahci DRIVER_MODULE

Name each ahci driver uniquely.
This remove the warning printed at each arm boot :
module_register: cannot register simplebus/ahci from kernel; already loaded from kernel

arm: Fix duplicate ehci DRIVER_MODULE

MFC r328201:

Convert extres/phy to kobj model. Similarly as other extres pseudo-drivers,
implement phy by using kobj model. This detaches it from provider device, so
single device driver can export multiple different phys. Additionally, this
allows phy to be subclassed to more specialized drivers, like is USB OTG phy,
or PCIe phy with hot-plug capability.

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

MFC r302584 (jmcneill):

Remove unused bus_space prototypes.

MFC r309029:

Do not attempt to disable/release clock if it had not been enabled.
While here fix a style(9) issue.

MFC r307518:
Fix device delete child function.

When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().

Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.

While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

r302523:
Add clk_get_by_ofw_node_index, which is like clk_get_by_ofw_index but
operates on a specific OF node instead of the pass in device's OF node.
r302528:
EXTRES: Add OF node as argument to all <foo>_get_by_ofw_<bar>() functions.
In some cases, the driver must handle given properties located in specific
OF subnode. Instead of creating duplicate set of function, add 'node' as
argument to existing functions, defaulting it to device OF node.

Enable USB PHY regulators when requested by the host controller driver.

Previously the USB PHY driver would enable all regulators at attach time.
This prevented boards from booting when powered by the USB OTG port, as
it didn't take VBUS presence into consideration.

Add support for Allwinner H3 SoC.
For now clocks, GPIO, Pinmux, UART, MMC, EHCI is supported.

Add support for the Allwinner A83T (sun8iw6p1) SoC.

Clocks, GPIO, UART, SD card / eMMC, USB, watchdog, and ethernet are
supported. Note that the A83T contains two clusters of four Cortex-A7
CPUs, and only CPUs in first cluster are started for now.

Tested on a Sinovoip Banana Pi BPI-M3.

Add support to enable/disable both the EHCI and OHCI Allwinner clocks. This
adds a lock to ensure only a single device is accessing the hardware. A
reference count is added to only enable when we start to use the clock,
and to disable after we have finished needing the clock.

This was extracted from a larger review to add OHCI support to the
Allwinner SoCs.

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.
