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.
