[PATCH v4 2/2] staging: greybus: resolved checkpatch checks for light.c

[Rachit Dhar <rchtdhr@gmail.com>]

Added comments to mutex declarations, to resolve the associated checkpatch.pl checks:

CHECK: struct mutex definition without comment
+       struct mutex                    lock;

CHECK: struct mutex definition without comment
+       struct mutex            lights_lock;
