drm/i915/gvt: make dpcd_fix_data supports DP1.2
GVT-g will emulate a fixed DPCD data to VM for DP/eDP panel. Update this data to latest DP1.2 with the maximum lane bandwidth of 5.4G/s to support 4K resolution in VM. V3: modify patch comment V2: add inline comment to describe the dpcd_fix_data. Signed-off-by: Pei Zhang <pei.zhang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
