[RFC 10/10] drm: test: Simplify testing on UML with kunit.py

[Michał Winiarski]

DRM depends on IOMEM and DMA, introduce an additional Kconfig to pull in
IOMEM and DMA emulation on UML.
Also, add .kunitconfig to simplify running DRM tests with:
./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm
