To allow bigger 64 bit prefetchable PCI regions in Linux, this patch
changes the base address and range of the ACPI area passed to Linux.
BayTrail can only physically access 36 bit of PCI address space. So
just chaning the range without changing the base address won't work
here, as 0xf.ffff.ffff is already the maximum address.
With this patch, a maximum of 16 GiB of local DDR is supported. This
should be enough for all BayTrail boards though.

This is needed for the PCIe hotplug to work correctly on some boards
with the newer Linux kernel versions.

I cannot find 'hpmemprefsize' as a kernel command line parameter, so I
assume removing it does not introduce any issue.

To enable the root device selection (kernel cmd-line) via PARTUUID, this
patch enables CMD_PART on all missing theadorable-x86 boards and
changes the default environment to generate the root=PARTUUID string
automatically.
This fixes problems that have been noticed on systems with multiple
SATA/AHCI controller connected via PCIe, where the device name for the
root device / partition (/dev/sdaX) was incorrect.

The build breaks because its not fitting the U-Boot binary into the ROM
image. So lets move VGA BIOS a bit to make room for the grown U-Boot
binary.
