pinctrl/nomadik: use simple or linear IRQ domain
This alters the Nomadik pinctrl driver to: - Call irqdomain_add_linear() for the DT case so we get all independent from IRQ numbers in this case. - Call irqdomain_add_simple() for the legacy case, which allocates the IRQ descriptors for the Nomadik pin controller dynamically.
