drm: Rename DP_PSR_SELECTIVE_UPDATE to better mach eDP spec

DP_PSR_EN_CFG bit 5 aka "Selective Update Region Scan Line Capture
Indication" in eDP spec has a ambiguous name, so renaming to better
match specification.

While at it, replacing bit shit by BIT() macro and adding the version
some registers were added to eDP specification.
