drm/i915: vlv: W/a for hotplug/manual VGA detection
VGA detection requires the reference clock to be on, so make sure this is the case. This fixes VGA hotplug/manual detection where all pipes are off and so we would normally disable all clocks. v2: - Instead of disabling PSR clock gating, force the reference clock on through the DPLL_A register. (Kin Chan S <[email protected]>) v3: - Move enabling of the clock to intel_reset_dpio() and use the DPLL_B register instead, where we already have a similar tweak for the CRI clock.
