Subject: [PATCH v3] gpu/drm_memory: fix a few warnings

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

Fix it by adding the MIT SPDX identifier without touching the boilerplate
language.

Suggested-by: Thomas Gleixner <tglx@...utronix.de>

v3: Keep the boilerplate language.
v2: Remove the redundant description of the license.
