[0/2] drm/i915/display: Add comparison for pipe config for MTL+ platforms

Currently, we may bump into pll mismatch errors during the
state verification stage. This happens when we try to use
fastset instead of full modeset. Hence, we would need to add
a check for pipe configuration to ensure that the sw and the
hw configuration will match. In case of hw and sw mismatch,
we would need to disable fastset and use full modeset instead.

However, first we need to revert the patch that disables fastset
for C10.
