Fix two remaining issues with the arm UFS mount issue:

- Add the GEOM_PART_GPT option and enable MSDOSFS in the GUMSTIX
kernel. [1]

- Add GEOM_LABEL to the PANDABOARD kernel, that should have been
included included in r285132. I confused the kernel configuration
used for the WANDBOARD and PANDABOARD, which the former uses the
IMX6 kernel configuration, along with the CUBOX-HUMMINGBOARD.

This is a direct commit to stable/10, as was r285132.

[1] I do not actually have the GUMSTIX board, but I suspect it will
fail to boot in the same way as the others have been.

Add the GEOM_LABEL option to the BEAGLEBONE, GUMSTIX, and RPI-B
kernel configuration files, resolving an issue where the UFS and
MSDOSFS partitions would not mount as set in fstab(5).

This is a direct commit to stable/10, as the GEOM_LABEL option
is handled differently in head for arm/armv6. The WANDBOARD
and PANDABOARD already have this kernel option entry via the IMX6
kernel configuration file, so do not need to be changed.

In kernel config files, it is supposed to be 'options<space><tab>' not
'options<tab><tab>', per long standing (but recently not so strictly
enforced) convention.

Strip arm/conf/DEFAULTS down to just items that are mandatory for running
the architecture.

Move all the files named foo/common.c to foo/foo_common.c

Initial cut for DTS on the hl201 board.

Add commented out dts for sam9260ek as well as early printf support.

Make clock optional on uart nodes, then back it out ("I don't know what I
was thinking, but it is lame.")

Set the baud rate if it isn't 0

Make at91_soc_id() public.

Properly round at91 resource on unmapping.

Move AT91 AIC related stuff to own file.

Fix another bug in multicast filtering. i.MX uses 6 bits from MSB in
LE CRC32 for the hash value, not the lowest 6 bits in BE CRC32.

Follow r262916 with one more config file that references a renamed common.c

Remove bogus AT91 define that causes compile errors. Most of the defines
for SAM9X are going away soonish anyway (once FDT works), but until
then...

Remove all dregs of a per-thread undefined-exception-mode stack.

Rework the VFP code that handles demand-based save and restore of state.

Always call vfp_discard() on thread death.

When a thread begins life it doesn't own the VFP hardware state on any cpu.

Make undefined exception entry MP-safe.

Fix the name of the dts file for the HL201...

When mapping an address, the bsh needs the same offset we do for other things.

Add explicit depends on bus_if.h and device_if.h to avoid a
chicken and egg problem in some compilation environments.

Switch to using PAs rather than VAs for the addresses we map for
devices. This is a nop, except for what's reported by atmelbus for the
resources.

Comment cleanups. Move things around for diff reduction against FDT work.
