Patrick Rudolph 6d787c2590 lib/fmap: Cache FMAP in cbmem 
For platform independend exposure of FMAP through a kernel module
cache the FMAP in CBMEM. In addition add a pointer in coreboot tables
pointing to the introduced CBMEM area.

To not waste the allocated DRAM, use the cached CBMEM in RAM enabled
stages if possible.

Tested on qemu using
https://github.com/9elements/linux/commits/google_firmware_fmap2

Tested on QEMU and Supermicro X11SSH-TF.
