[igt-dev] [PATCH i-g-t] tests/kms_plane_cursor: Use dprx CRC for AMDGPU

[Rodrigo Siqueira]

We have some CRC errors spread around a few IGT tests related to a
driver bug; we have a kernel fix for that [1]. However, after applying the
kernel patch, all tests related to pipe-a-primary-size-* start to fail.
To fix this issue, we need to make kms_plane_cursor utilize DPRX CRC;
this commit updates this test by basically setting DPRX for amdgpu.
