nb/intel/sandybridge: Make the mainboard_rcba_config hook optional

This also changes the name to mainboard_late_rcba_config to better
reflect what it does.

This adds an empty weakly linked default. The rationale behind this
change is that without an implementation of the hook some features
might not work but that the result is likely still able to boot, so it
can be made optional.
