[ Upstream commit 0ff9f49646353ce31312411e7e7bd2281492a40e ]
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.
Fixes: d1667b86795a ("drm/hisilicon/hibmc: Add support for frame buffer")
