Relocate the alink access functions out of stoneyridge where they
were dead code. This source maintains the ability to access all
register spaces, however more modern APUs define only ABCFG in
the BKDGs.

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.

Convert smbus_read8() and smbus_write8() functions to use the same
arguments as the other AcpiMmio blocks, and add 16 and 32 bit versions.
Add matching functions for the ASF controller.

These resolved to <device/oprom/include/io.h> which
included <arch/io.h> that we really wanted.

Currently SMBUS registers are accessed through IO, but with stoneyridge
they can be accessed through MMIO. This reduces the time of execution by
a tiny amount (MMIO write is faster than IO write, though MMIO read is about
as fast as IO read) as most of the time consumed is actually transaction
time. Convert code to MMIO access.
BUG=b:117754784
TEST=Used IO to write and MMIO to read, to confirm a one to one relationship
between IO and MMIO. Then build and boot grunt.

Solve issues left from Change-Id Ib88a868e654ad127be70ecc506f6b90b784f8d1b
Unify code: smbus.c to have the actual execution code, sm.c and smbus_spd.c
call functions within smbus.c.
Fix some functions that wrongly use SMBHSTCTRL as the register for the
data being transfered. The correct register is SMBHSTDAT0.
Include file smbus.h should only be used by sm.c, smbus.c and smbus_spd.c.

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
