[PATCH 2/3] drm/hisilicon: hibmc: Don't overwrite fb helper surface depth

[John Garry]

Currently the driver overwrites the surface depth provided by the fb
helper to give an invalid bpp/surface depth combination.

This has been exposed by commit 70109354fed2 ("drm: Reject unknown legacy
bpp and depth for drm_mode_addfb ioctl"), which now causes the driver to
fail to probe.

Fix by not overwriting the surface depth.
