	Mask the ERR_FATAL_MASK before scaler initialization.
After enabling the scaler and waiting for one frame,
unmask the previously masked bits, PS_ECC and
ERR_FATAL_MASK
Unmasking of ERR_FATAL_MASK bit is use for
validation purpose. There is no functional
impact.
v2: Remove intel_display_need_wa[Jani]
    Optimize the ecc_unmask call[Animesh]
v3: Add intel_display_wa[Jani]
