SeaBIOS ACPI patch fixing Ubuntu/Windows installs

Bin Meng posted an 18-part patch to the SeaBIOS list, fixing multiple issues that may impact the installation of Ubuntu (only Ubuntu and no other Linux distros??) and Windows:

[PATCH v2 00/18] x86: acpi: Support installation of Ubuntu/Windows and boot Windows

SeaBIOS can be loaded by U-Boot to aid the installation of Ubuntu and Windows to a SATA drive and boot from there. But till now this is broken. The installation either hangs forever or just crashes. This series fixed a bunch of issues that affect the installation of Ubuntu and Windows, and booting Windows.

Testing was performed on MinnowMax by:
– Install Ubuntu 14.04 and boot
– Install Windows 8.1 and boot
– Install Windows 10 and boot

This series is available at u-boot-x86/acpi2-working.

Changes in v2:
– New patch to remove the unnecessary checksum calculation of DSDT
– New patch to remove header length check when writing tables
– New patch to enable SeaBIOS on all boards
– New patch to add GPIO ASL description
