Unify coreboot table generation
coreboot tables are, unlike general system tables, a platform independent concept. Hence, use the same code for coreboot table generation on all platforms. lib/coreboot_tables.c is based on the x86 version of the file, because some important fixes were missed on the ARMv7 version lately.
