From: Linus Walleij <linus.walleij@linaro.org>

This converts the Nomadik and Ux500 over to using sparse IRQ,
including some pokes around the pinctrl driver. To avoid
referencing unnecessary header files, the plat-nomadik timer
driver is augmented to pass an irq number at init time, and
the change is applied across both platforms simultaneously
for this reason.
