Stoney Ridge Platforms: Make AGESA callout tables common

There was no reason to have the AGESA callout tables in each mainboard,
so move them to soc/amd/common.

Move chip specific functions into the stoneyridge directory:
- agesa_fch_initreset
- agesa_fch_initenv
- agesa_ReadSpd

Combine agesa_ReadSpd and agesa_ReadSpd_from_cbfs, and figure out which
to use.

Soldered-down memory still needs to be supported in a future commit, as
stoney supports both DDR3 & DDR4.  A bug has been filed for support for
the upcoming Grunt platform.
