[PATCH v2] gpu/drm_memory: fix a few warnings

[Qian Cai <cai@lca.pw>]

The opening comment mark "/**" is reserved for kernel-doc comments, so
it will generate a warning with "make W=1".

drivers/gpu/drm/drm_memory.c:2: warning: Cannot understand  * \file
drm_memory.c

Also, silence a checkpatch warning by adding a license identfiter where
it indicates the MIT license further down in the source file.

WARNING: Missing or malformed SPDX-License-Identifier tag in line 1

It becomes redundant to add both an SPDX identifier and have a
description of the license in the comment block at the top, so remove
the later.

v2: remove the redundant description of the license.
