drm/vc4: tests: Fix UAF in the mock helpers
The VC4 mock helpers allocate the CRTC, encoders and connectors using a
call to kunit_kzalloc(), but the DRM device they are attache to survives
for longer than the test itself which leads to use-after-frees reported
by KASAN.
Switch to drmm_kzalloc to tie the lifetime of these objects to the main
DRM device.
