ARM: plat-nomadik: handle clocking properly
clk_prepare() was missing from the Nomadik MTU driver, also handle errors on prepare and enable in the simplest way possible, by bugging out - we cannot start the system without time anyway. Acked-by: Alessandro Rubini <rubini@unipv.it> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
