From: Vathsala Nagaraju <vathsala.nagaraju@intel.com>

Adds new psrwake options defined in the below table.
Platform	PSR wake options vbt version
KBL/CFL/WHL	All
SKL		All PV releases (Check for 203+ might help but cannot be foolproof)
BXT		Uses old interpretation.
CNL/ICL+	All
GLK		All

For SKL, we will continue to use older interpretation for the above reason.

v2: Jani
    Keep the bdb version check.
