drm/i915/vlv: Workaround a punit issue in DDR data rate for 1333.
For DDR data rate reporting by Punit in PUNIT_GPU_FREQ_STS, the actual
data encoding is 00b=800, 01b=1066, 10b=1333, 11b=1333.
Some premium VLV sku will get the DDR_DATA_RATE set as 11. As a result,
the turbo frequency reporting will be incorrect without this workaround.
