[Intel-gfx] [PATCH] Revert "drm/i915/vlv: fixup DDR freq detection per Punit spec"

[deepak.s at linux.intel.com]

From: Deepak S <deepak.s at linux.intel.com>

This reverts commit f64a28a7c5ab2fc342326de9e126acf3cc0f91d6.

As per the inputs provided by hardware team  we still use DDR
Rates as 0,1=800, 2=1066, 3=1333.
With this change, Turbo freqs used on current machines matches.
