From: chandra konduru <chandra.kond...@intel.com>

This patch adds necessary prep work for nv12 testcase:
  - updated fb allocation functions to handle NV12 format
  - igt helper function to return png image size
  - igt helper function to calculate start of uv in a given NV12 buffer
  - igt helper function to map buffer for host access
  - populates fb->...[4] parameters for NV12
  - igt helper function to convert RGB data to NV12
  - updated drm_format to bpp to handle NV12
  - updated fast copy blit function to deal NV12 subplanes
  - made an update to kms_render testcase due to above changes
