Currently we disable the VGA plane from various places, sometimes multiple times in the same init/resume sequence. Get rid of all this mess and do it just once. The most correct place seems to be just after intel_early_display_was() as that one applies various workarounds that need to be in place before we touch any planes (including the VGA plane). Actually, we do still have a second caller in vlv_display_power_well_init(). I think we still need that as the reset value of VGACNTR is 0x0 and thus technically the VGA plane will be (at least partially) enabled after the power well has been toggled. In both cases we have the necessary power reference already held (INIT power domain for load/resume case, and the display power well itself being what we need for vlv_display_power_well_init()).
