drm/i915/psr: Update PSR module parameter descriptions

Browse Source 
We are re-using PSR module parameters for panel replay. Update module
parameter descriptions with panel replay information:

enable_psr:

-1 (default) == follow what is in VBT
0 == disable PSR/PR
1 == Allow PSR1 and PR full frame update
2 == allow PSR1/PSR2 and PR Selective Update

enable_psr2_sel_fetch

0 == disable selective fetch for PSR and PR
1 (default) == allow selective fetch for PSR PR
