[Intel-gfx] [PATCH v2 03/11] drm/i915: Polish some RMWs

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Doing the if-else around RMWs is kinda silly. Just set/clear the
apporiate bits with a single RMW.

Also unify the coding style a bit icl_wa_cursorclkgating() while at it.
