[ Upstream commit f0fd848342802bc0f74620d387eead53e8905804 ]
Unbinding components (i.e. mtk_dsi and mtk_disp_ovl/rdma/color) will trigger master(mtk_drm)'s .unbind(), and currently mtk_drm's unbind won't actually unbind components. During the next bind, mtk_drm_kms_init() is called, and the components are added back.
.unbind() should call mtk_drm_kms_deinit() to unbind components.
And since component_master_del() in .remove() will trigger .unbind(), which will also unregister device, it's fine to remove original functions called here.
