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.
