soc/amd/stoneyridge: Split sata functionality

Separate chipset-specific source from sata_init(), and modify it
to better match coreboot conventions.  A subsequent patch will
move the generic portion to soc/amd/common.

The support for enabling port multipliers appears to have been
first added for Kabini.  Although missing from the documentation,
the ability to affect the HBA Capabilities Register seems to remain
for Stoney Ridge.
