Vendor only does dummy reads right after JEDEC init is finished
and dram init was marked as finished.
Dummy reads also make much more sense after JEDEC init as a way to
send a few JEDEC commands, presumably as a way to make sure it is
ready.

Add explicit CBMEM_STAGE_CACHE option. Rename
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE.
Platforms with SMM_TSEG=y always need to implement
stage_cache_external_region(). It is allowed to return with a
region of size 0 to effectively disable the cache.
There are no provisions in Kconfig to degrade from
TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE.
As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower
S3 resume speed unless they explicitly select the option.

the MEM_CLOCK_800MHz case isn't needed, since that is explicitly checked
and avoided before the while loop. With that gone, only the
667MHz/default case is left, which we don't need to switch over anymore.

die now than return 0, which will cause a division-by-zero error
later on where this function is called. The first two speeds are also
unsupported and have the same problem with returning 0, so die on those
as well.
