In the current code, at haswell_modeset_global_resources, first we decide if we want to enable/disable the power well, then we decide if we want to enable/disable PC8. On the case where we're enabling PC8 this works fine, but on the case where we disable PC8 due to a non-eDP monitor being enabled, we first enable the power well and then disable PC8. Although wrong, this doesn't seem to be causing any problems now, and we don't even see anything in dmesg. But the patches for runtime D3 turn this problem into a real bug, so we need to fix it. This fixes the "modeset-non-lpsp" subtest from the "pm_pc8" test from intel-gpu-tools. v2: - Rebase (i915_disable_power_well). v3: - More reabase.
