Invoke drm_plane_helper_funcs.end_fb_access before
drm_atomic_helper_commit_hw_done(). The latter function hands over
ownership of the plane state to the following commit, which might
free it. Releasing resources in end_fb_access then operates on undefined
state. This bug has been observed with

ltdc_load() calls functions drm_crtc_init_with_planes(),
drm_universal_plane_init() and drm_encoder_init(). These functions
should not be called with parameters allocated with devm_kzalloc()
to avoid use-after-free issues [1].
Use allocations managed by the DRM framework.
Found by Linux
Create rotation property according to the hardware capability.
Since currently OVL of all chips support same rotation,
no need to define it in the driver data.

This commit is based on 20231024130048.14749-1-shawn.s...@mediatek.com.
This bug was found when running IGT tests.
For CRTCs that doesn't support rotation should still return
DRM_MODE_ROTATE_0, otherwise the test will fail to restart.
Returns the hardware capabilities accordingly.
