[PATCH 2/2] drm/i915: Add functions to execute the new sequences from VBT

[Deepak M <m.deepak@intel.com>]

From: Gaurav K Singh <gaurav.k.singh@intel.com>

New sequences are added in the mipi sequence block of the
VBT from version 3 onwards. The sequences are added to
make the code more generic as the panel related info
are placed in the VBT.
