[PATCH] pinctrl/nomadik: use irq_create_mapping()

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

Since in the DT case, the linear domain path will not allocate
descriptors for the IRQs, we need to use irq_create_mapping()
for mapping hwirqs to Linux IRQs, so these descriptors get
created on-the-fly in this case.
