9d0cc2aea9 cbfs: Introduce cbfs_ro_map() and cbfs_ro_load()
This patch introduces two new CBFS API functions which are equivalent to
cbfs_map() and cbfs_load(), respectively, with the difference that they
always operate on the read-only CBFS region ("COREBOOT" FMAP section).
Use it to replace some of the simple cases that needed to use
cbfs_locate_file_in_region().

6615c6eaf7 mrc_cache: Move code for triggering memory training into mrc_cache
Currently the decision of whether or not to use mrc_cache in recovery
mode is made within the individual platforms' drivers (ie: fsp2.0,
fsp1.1, etc.).  As this is not platform specific, but uses common
vboot infrastructure, the code can be unified and moved into
mrc_cache.  The conditions are as follows:

  1.  If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain
      switch is true)
  2.  If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this
      means that memory training will occur after verified boot,
      meaning that mrc_cache will be filled with data from executing
      RW code.  So in this case, we never want to use the training
      data in the mrc_cache for recovery mode.
  3.  If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this
      means that memory training happens before verfied boot, meaning
      that the mrc_cache data is generated by RO code, so it is safe
      to use for a recovery boot.
  4.  Any platform that does not use vboot should be unaffected.

Additionally, we have removed the
MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the
mrc_cache driver takes care of invalidating the mrc_cache data for
normal mode.  If the platform:
  1.  !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data
  2.  HAS_RECOVERY_MRC_CACHE, only invalidate if retrain switch is set

BUG=b:150502246
BRANCH=None
TEST=1. run dut-control power_state:rec_force_mrc twice on lazor
        ensure that memory retraining happens both times
        run dut-control power_state:rec twice on lazor
        ensure that memory retraining happens only first time
     2. remove HAS_RECOVERY_MRC_CACHE from lazor Kconfig
        boot twice to ensure caching of memory training occurred
	on each boot.
