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.

Add an `amdblocks` internal API and rename
soft_reset() => warm_reset()
hard_reset() => cold_reset()
as these terms are commonly used in the surrounding code.
On Stoney Ridge, make board_reset() call cold_reset() to keep
current behaviour of common code calling hard_reset(). But add
a TODO if this is intended.
Note: Stoney Ridge is using CF9 for the actual reset but the
configuration for a cold reset doesn't use the usual full reset
bit but some other mechanism.

Extend the existing reset handling features in Stoney Ridge to plan for,
and recognize, warm resets. The ColdRstDet bit is always zero on a cold
reset, and is intended as a mechanism for the BIOS to determine the type
of a reset that occurred.
Set ColdRstDet=1 after all cores have been initialized, so that any
subsequent reset may be identified as warm/cold. A later patch will check
the value during mp_init.

- Move #defines to soc/northbridge.h, add other reset definitions to
soc/southbridge.h.
- Clean up file to use definitions instead of magic numbers.
- Add do_soft_reset()

Simplify funciton names and remove reference to hudson in stoneyridge.
The southbridge in Stoney Ridge is Kern and hudson naming is
no longer accurate.

Correct the majority of reported errors and mark most of the
remaining ones as todo. (Some of the lines requiring a >80
break are indented too much currently.) Some of the alignment
in hudson.h still causes checkpatch errors, but this is
intentionally left as-is.
Also make other misc. changes, e.g. consistency in lower-case
for hex values, using defined values, etc.
These changes were confirmed to cause no changes in a Gardenia
build. No other improvements were made, e.g. changing to helper
functions, or converting functions like __outbyte().

Copy the Hudson/Kern code from southbridge/amd/pi/hudson. This
is the first of a series of patches to migrate Stoney Ridge
support from cpu, northbridge, and southbridge to soc/
Changes:
- add soc/amd/stoneyridge and soc/amd/common
- remove all other Husdon versions
- update include paths, etc
- clean up Kconfig and Makefile
- create chip.c to contain chip_ops
