drm/i915: only run hsw_power_well_post_enable when really needed



Only run it after we actually enable the power well. When we're
booting the machine there are cases where we run
hsw_power_well_post_enable without really needing, and even though
this is not causing any real bugs, it is unneeded and causes confusion
to people debugging interrupts.
