From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Separate the part that calculates the register values from the part that
writes the registers. This will be useful in the atomic page flip code.
Also move the watermark magic into a prepare function that can be
performed outside the critical parts of the atomic page flip code.
