Add functionality for reading in the coreboot tables and storing their
contents in a structure for easy access.

These four patches add support for the 32 bit Linux boot protocol to the
zboot command. They also add support for an initrd.

Changes in v2:
- Move arch/x86/include/asm/ic/coreboot/* to
arch/x86/include/asm/arch-coreboot/*
- Merge the lib_sysinfo change into this one.
- Changed includes to match ic/coreboot => arch-coreboot move.
- Merged a previous change that used the coreboot tables to approximate
total RAM size into this one.
- Moved the coreboot specific e820 function into a different patch.
- Moved the coreboot specific e820 function into this patch.
- Add a help message to the zboot command.

Changes in v3:
- Moved the coreboot specific e820 function declaration out of the header.
- Moved the coreboot specific e820 function declaration into this patch.
