[igt-dev] [PATCH i-g-t 4/4] tests/i915/gem_linear_blits: Enable XY_FAST_COPY_BLT copy instruction

[Vikas Srivastava]

From: Arjun Melkaveri <arjun.melkaveri at intel.com>

Test case uses legacy command XY_SRC_COPY_BLT_CMD which is
not supported on newer platforms. Modified test to
use XY_FAST_COPY_BLT.
