This registers offsets is not sequential for transcoder D and EDP so
for EDP transcoder it was writing to 0x420d0 that do not map to
any register in spec.
CHICKEN_TRANS is used in PSR2 and intel_enable_ddi_hdmi() to apply
WA #1143 but I'm not aware of any open issue cause by this offset
error.
Spec: 7524
