[igt-dev] [PATCH v2 4/4] test/kms_atomic: Skip plane overlay test for amdgpu

[Rodrigo Siqueira]

Currently, amdgpu does not support an overlay strategy. As a result,
plane_overlay fails on amdgpu; since this is a driver limitation, this
commit skips the overlay test for amdgpu.

Changes since V1:
- Improve skip message
