drm/tegra: tegra_drm.h: fix all uapi kernel-doc warnings

Add 2 struct member descriptions and convert #define macro constants
comments to kernel-doc comments to eliminate all kernel-doc warnings:

Warning: include/uapi/drm/tegra_drm.h:353 struct member 'cmdbuf' not
 described in 'drm_tegra_reloc'

 described in 'drm_tegra_reloc'
