lynxpoint: Add power management helper functions
There are subtle yet significant differences in some of the
registers in the power management region between LynxPoint-H
and LynxPoint-LP.
In order to reduce code that is accessing these registers and
would need special cases this adds a number of helper functions
that can be used in both ramstage and SMM.
This commit just adds the new functions, subsequent commits will
start to use them.
