drm/ttm/tests: Set DMA mask in KUnit device

Browse Source 
In commit d393acce7b ("drm/tests: Switch to kunit devices"),
DRM test helpers migrated away from using a dummy platform driver
in favour of KUnit device. This means that DMA masks for the device
are not set but are required by ttm_pool_alloc tests.

Set the DMA mask for coherent mappings to unblock testing.
