Adds new psrwake options defined in the below table.
Platform PSR wake options vbt version
KBL/CFL/WHL All(205+)
BXT Uses old interpretation.
CNL/ICL+ All(205+)
GLK All(205+)
SKL All PV releases (Check for 205+ might help but cannot be foolproof)
We will continue with newer interpretation for SKL from 205.
v2: Jani
Keep the bdb version check.
v3:
Apply newer version for skl from 205+(DK).
Add (version check && platform list) (Jani).
Add bdb version for each platform in commit message(DK).
