gpio: nomadik: support shared GPIO IRQs
Support a single IRQs used by multiple GPIO banks. Change the IRQ
handler type from a chained handler (as used by gpiolib
for ->parent_handler) to a threaded IRQ.
Use the generic_handle_domain_irq_safe() helper. The non-safe version
must be called in a no-IRQ context.
The Mobileye EyeQ5 platform uses this GPIO controller and share an IRQ
for its two banks.
