soc: Add AMD Stoney Ridge southbridge code
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
