On non-DT platforms IRQ controllers associated with the GPIOs have a fixed IRQ base value known at compile time. The sh-pfc driver translates GPIO number to IRQ numbers using a hardcoded table. This mechanism breaks on DT platforms, as the IRQ base values are dynamic in that case. Fix this by specifying IRQs associated with GPIOs in IRQ resources, populated automatically from the device tree. When IRQ resources are specified the driver requires one IRQ resource per GPIO able to generate an interrupt, and uses the translation table to compute the IRQ resource offset instead of the IRQ number.
