drm/i915/psr: Check if VBT says PSR can be enabled.

Browse source

Driver features data block has a boolean flag for PSR, use this to decide
whether PSR should be enabled on a platform. The module parameter can
still be used to override this.

Note: The feature currently remains disabled by default for all platforms
irrespective of what VBT says.
