drm/i915/display: Move psr related module parameters under display

Move psr related module parameters under display. Also fix error in
enable_psr2_sel_fetch module parameter descrtiption. It was saying disabled
by default while it's vice versa. Also psr_safest_params was missing
default value in description. This is now added.

v2:
  - Fix enable_psr2_sel_fetch description.
  - Add default value into psr_safest_params description.
