drm/msm: fix potential deadlock in gpu init
Somewhere along the way, the firmware loader sprouted another lock
dependency, resulting in possible deadlock scenario:
&dev->struct_mutex --> &sb->s_type->i_mutex_key#2 --> &mm->mmap_sem
which is problematic vs things like gem mmap.
So introduce a separate mutex to synchronize gpu init.
