[PATCH] drm/i915/display: Skip C10 state verification in case of fastset

[Mika Kahola]

PLL's are not programmed in case of fastset so the state
verfication compares bios programmed PLL values against
sw PLL values. To overcome this limitation, we can skip
the state verification for C10 in fastset case as the
driver is not writing PLL values.
