arch: introduce architecture dependent common variables

Stefan and others have discussed their interest in only
including options in Kconfig that are directly associated
with building a coreboot image. There are variables that
are architecture dependent that are utilized in the
coreboot infrastructure. To meet that goal, introduce
<arch/cbconfig.h> header file which defines variables
for the coreboot infrastructure that are architecture
dependent but utilized in common infrastructure.
