Move the stoneyridge AcpiMmio code into soc/amd/common.
The SB800 southbridge introduced the MMIO hardware blocks at 0xfed80000
commonly known as AcpiMmio. Implementations beginning with Mullins
enable decode in PMx04. Older designs use PMx24 and allow for
configuring the base address. Future work may support the older version.
Comparing the documentation for AMD's RRGs and BKDGs, it is evident that
the block locations have not been reassigned across products. In some
cases, address locations are deprecated and new ones consumed, e.g. the
early GPIO blocks were simpler at offset 0x100 and the newer GPIO banks
are now at 0x1500, 0x1600, and 0x1700.
Note: Do not infer the definitions within the hardware blocks are
consistent across family/model products.

Previously broadwell used a romcc bootblock and starting verstage in
romstage was madatory but with C_ENVIRONMENT_BOOTBLOCK it is also
possible to have a separate verstage.
This selects using a separate verstage by default but still keeps the
option around to use verstage in romstage.
With a separate verstage the romstage becomes an RW stage.
The mrc.bin however is only added to the RO COREBOOT fmap region as it
requires to be run at a specific offset. This means that coreboot will
have to jump from a RW region to the RO region for that binary and
back to that RW region after that binary is done initializing the
memory.

As of CL:1605641, vboot2 code should be used for setting and
checking display init state. Remove all vboot1 OPROM-related
code, and use the vboot2 display init code which has already
been added in previous commits.
coreboot should not be reading vboot NVRAM flags directly.
Remove the function vboot_wants_oprom(), and instead rely on
display_init_required(), which uses the
VBOOT_WD_FLAG_DISPLAY_INIT value stored in
vboot_working_data.flags, initialized during verstage.
Note that this means in the case of CONFIG_VBOOT=y, the return
value of display_init_required() can only be trusted after
verstage has been executed. This should not be a problem
assuming that all display initialization occurs in ramstage.

granularity from 16 ticks to 8 ticks, which implies bad margin
