[Intel-gfx] [PATCH 1/2] drm/i915/glk: Calculate high/low switch count for GLK

As per BSPEC, high/low switch count to be programmed in terms of byteclock using exit_zero_count and prep_count. For Geminilake exit/prep counts are already calculated in terms of byteclock. This patch calculates high/low switch count using counts value in byteclock, old calculation leads to screen
