Insert a postcar stage for Stoney Ridge and move romstage's CAR
teardown there.
The AMD cache-as-ram teardown procedure currently uses a wbinvd
instruction to send CAR contents to DRAM backing. This allows
preserving stack contents and CAR globals after the teardown
happens, but likely results in memory corruption during S3 resume.
Due to the current base of the DCACHE region, reverting to an
invd instruction will break the detection mechanism for CAR
migrated variables. Using postcar avoids this problem.
The current behavior of AGESA is to set up all cores' MTRRs during
the AmdInitPost() entry point. This implementation takes control
back and causes postcar's _start to clear all settings and set
attributes only for the BIOS flash device, TSEG, and enough space
below cbmem_top to load and run ramstage.

Change the Stoney Ridge SOC to a more modern method for setting up
the multiple cores.
Add a new cpu.c file for most of the processor initiliazation. Build
mp_ops with the necessary callbacks. Note also that this patch removes
cpu_bus_scan. Rather than manually find CPUs and add them to the
devicetree, allow this to be done automatically in the generic
mp_init.c file.
SMM information is left blank in mp_ops to avoid having mp_init.c
install a handler at this time. A later patch will add TSEG SMM
capabilities for the APU.
This patch also contains a hack to mask the behavior of AGESA which
configures the MTRRs and Tom2ForceMemTypeWB coming out of AmdInitPost.
The hack immediately changes all WB variable MTRRs, on the BSP, to UC
so that all writes to memory space will make it to the DRAM.

Move the mainboard romstage functionality into the soc directory
and change the function name to be compatible with the call
from assembly_entry.S. Drop the BIST check like other devices.
Move InitReset and InitEarly to bootblock. These AGESA entry
points set some default settings, and release/recapture the
AP cores. There are currently some early dependencies on
InitReset. Future work should include:
* Pull the necessary functionality from InitReset into bootblock
* Move InitReset and InitEarly to car_stage_entry() and out of
bootblock
- Add a mechanism for the BSP to give the APs an address
to call and skip most of bootblock and verstage (when
available) (1)
- Reunify BiosCallOuts.c and OemCustomize.c
(1) During the InitReset call, the BSP enables the APs by setting
core enable bits in F18F0x1DC and APs begin fetching/executing
from the reset vector. The BSP waits for all APs to also
reach InitReset, where they enter an endless loop. The BSP
sends a command to them to execute a HLT instruction and the
BSP eventually returns from InitReset. The goal would be to
preserve this process but prevent APs from rerunning early
code.
