drm/imx/lcdc: Fix double-free of driver data

Browse source

[ Upstream commit ff3670877e ]

The struct imx_lcdc driver data is allocated using devm_drm_dev_alloc()
so it must not be explicitly kfree()d.

Also drm_kms_helper_poll_fini() should not be called as there is no
matching drm_kms_helper_poll_init(). So drop the release function
completely.
