Julius Werner cefe89ee79 lib/fmap: Add optional pre-RAM cache
This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.

In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.

Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).
