[igt-dev] [PATCH i-g-t] tests/prime_self_import: Swap gtt mapping for cpu

[Antonio Argenziano]

The test uses gtt mapping to check two BOs have the same content, since
it seems there is no contention on the BOs use cpu mapping to make it
compatible with platforms that do not have a mappable aperture.

v2:
	- Need to have an explicit set_domain. (Chris)
