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.
