southbridge/amd/sb700: Add option to disable SATA ALPM

The AMD Register Programming Reference states that the user should
have the option to disable Active Link Power Management for two
reasons.  First, some drives may not function correctly with the
ALPM implementation of the SP5100, and second there are some
situations where low latency access is more important than the
power savings created by using ALPM.

Allow the user to disable ALPM if desired.
