[Marshall Dawson (Code Review)]

Hello build bot (Jenkins),

https://review.coreboot.org/19755

to look at the new patch set (#3).

WIP soc/amd/common: Convert to C_ENVIRONMENT_BOOTBLOCK

Add dedicated CAR setup and teardown functions and, Kconfig
options to force their inclusion into the build.  The .S files
are effectively duplicated code from the cache_as_ram.inc file.

The .S files use global proc names in anticipation for use with
the Kconfig symbols C_ENVIRONMENT_BOOTBLOCK and POSTCAR_STAGE.

Move the mainboard romstage functionality into the soc directory
and change the function name to be compatible with the call
from assembly_entry.S.

Move InitReset and InitEarly to bootblock.  These AGESA entry
points set some default settings, and release/recapture the
AP cores.

todo:
 * preserve BIST
