[PATCH] drm/amd/amdgpu: Remove initialisation of globals to 0 or NULL

[Srinivasan Shanmugam]

Global variables do not need to be initialized to 0 or NULL and checkpatch
flags this error in drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:

ERROR: do not initialise globals to NULL
+char *amdgpu_disable_cu = NULL;
+char *amdgpu_virtual_display = NULL;

Fix this checkpatch error.
