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.

Please keep the version check.
Sure. For SKL , shall we use older interpretation for all bdb
version as
vbt team cannot confirm bdb version for SKL?
I guess.
Why not change the version check to >= 203, if that's what PV
releases
had as per your commit message? With the current code, Linux and
Windows set 500 us and 2.5 ms respectively on my laptop.
Said laptop is a SKL with bdb version 205.
+ ashutosh(VBT team)
Since VBT team cannot confirm version for SKL ,so skipped for skylake.
I did a copy paste of the table provided by vbt team, will edit for skylake.
