drm: Convert cmpxchg(bool) back to a two step operation
ARM v6 (at least) only allows cmpxchg on 32bit variables which doesn't
always include the bool type.
drivers/built-in.o: In function `vblank_disable_and_save':
imx-ocotp.c:(.text+0xb45e8): undefined reference to `__bad_cmpxchg'
Makefile:986: recipe for target 'vmlinux' failed
