[PATCH] video: ARM CLCD: fix Vexpress regression

[Linus Walleij <linus.walleij@linaro.org>]

The CLCD does not come up on Versatile Express as it does not
(currently) have a syscon node for controlling the block apart
from the CLCD itself. Make sure the .init() function can bail
out without an error making it probe again.
