[Intel-xe] [PATCH 08/31] 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.
