[Intel-gfx] [PATCH 1/9] drm/i915: Check for platform specific GPIO config

[Vidya Srinivas]

From: Uma Shankar <uma.shankar at intel.com>

Panel GPIO control should be done based on platform. Add a check
to restrict VLV and CHT specific GPIO confirguration, so that
they dont apply to other platforms.
