[Intel-gfx] [PATCH 4/4] drm/i915: DDI: call intel_edp_drrs_enable() on encoder updates

[Hans de Goede]

Call intel_edp_drrs_enable() on encoder updates to make sure that we enable
DRRS (when applicable) on fastsets.

Note calling intel_edp_drrs_enable() when PSR has already been enabled is a
no-op, so it is safe to do this on every encoder->update callback.
