Add support for VAR-SOM-OM44[1] SODIMM system on module from
Variscite. SoM features a OMAP4460, 1GB RAM, Gigabit Ethernet
(LAN7500) and optional WLAN/BT.

Also add support for VAR-STK-OM44 development board from
Variscite. This kit features a VAR-SOM-OM44 and the carrier board
VAR-OM44CustomBoard[2]. The VAR-STK-OM44 is the same as
VAR-DVK-OM44 but without the LCD display.

omap4-var-stk-om44.dts replace the old and very limited
omap4-var-som.dts.

The OMAP4/5 TRMs primarily list address offsets from the padconf
physical address (which is not driver base address) and not
always the absolute physical address for padconf registers like
some other OMAP TRMs. So create a new macro to use this offset
and to avoid confusion between different OMAP parts.

For more information, see the tables in TRM for named something like
"Device Core Control Module Pad Configuration Register Fields"
and "Device Wake-Up Control Module Pad Configuration Register Fields"

Note that we now also have to update cm-t54 for the fixed up
offsets.

With ARCH_OMAP2PLUS being separated out into OMAP2/3/4/5 etc all the TI device
tree blobs are built no matter the combination of SoCs that are enabled. This
often causes a bunch of irrelevant .dts to be built on a multi platform kernel,
this enables the building of just the ones relevant to the SoCs that are
actually enabled. It also orders the dts file alphabetically.

This also helps to avoid trivial merge conflicts when adding support
for new boards.

The kvm/mmu code shared by arm and arm64 uses kalloc() to allocate
a bounce page (if hypervisor init code crosses page boundary) and
hypervisor PGDs. The problem is that kalloc() does not guarantee
the proper alignment. In the case of the bounce page, the page sized
buffer allocated may also cross a page boundary negating the purpose
and leading to a hang during kvm initialization. Likewise the PGDs
allocated may not meet the minimum alignment requirements of the
underlying MMU. This patch uses __get_free_page() to guarantee the
worst case alignment needs of the bounce page and PGDs on both arm
and arm64.
