[igt-dev] [PATCH i-g-t 5/7] lib/intel_batchbuffer: Add wrapper API to use XY_FAST_COPY_BLT/XY_SRC_BLT

[Karolina Stolarek]

From: Vikas Srivastava <vikas.srivastava at intel.com>

Add wrapper API in intel_batchbuffer to call respective copy functions
for XY_FAST_COPY_BLT or XY_SRC_BLT based on platform on which its
supported.
