[coreboot-gerrit] Change in coreboot[master]: amd/pi: Add verstage support

[Marshall Dawson (Code Review)]

Hello build bot (Jenkins),

I'd like you to reexamine a change.  Please visit

    https://review.coreboot.org/18439

to look at the new patch set (#15).

Change subject: amd/pi: Add verstage support
......................................................................

amd/pi: Add verstage support

This patch takes hints from the work in commits:
 * 75c51d9 "x86: add standalone verstage support"
 * 909c512 "fsp1_1: add verstage support"

Give PI-based systems the capability of running a SEPARATE_VERSTAGE.
This adds
 * A verstage.c file to that initiates loading romstage (and verification)
 * A new entry point in car.c that will be used when there is a separate
   verstage
 * Makefile flags and verstage-y additions for cpu and southbridge
 * Besides AMD binary-PI changes, the x86 lapic timer is also now
   included into verstage

This has been tested on Stoney (00670F000) and Gardenia.  Although
additional APUs' makefiles are modified, none of those platforms are
assumed to support verstage at this time.

The AMD systems currently don't support C_ENVIRONMENT_BOOTBLOCK.
Once that has been added, portions of this patch can be backed out.
