drm/i915/psr: Adds psrwake options for all platforms

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).
