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).
