drm/i915: Disable CPU underruns around eDP port and vdd enable on ILK-IVB
We sometimes get a spurious CPU pipe underrun somewhere between
enabling port A and enabling vdd for the panel. Observed on both
ILK and IVB with port A eDP. Suppress FIFO underrun reporting
around the port and vdd enable to avoid the dmesg errors.
Not sure if port D eDP would suffer from the same issue, but assume
that it doesn't until proven differently.
Testcase: igt/kms_setmode
