With the added capabilty of the intc_irqpin driver to handle shared external IRQs, all prerequisites are fulfilled and we are ready to migrate completely to GIC. This includes the following steps: - Kconfig: select ARM_GIC and RENESAS_INTC_IRQPIN - intc-r8a7740: Throw out all legacy INTC code and init the GIC. We need to mask out all shared IRQs as it is needed by the shared intc_irqpin driver. - setup-r8a7740: Add 4 irqpin devices to handle external IRQs and update all IRQ numbers to point to the GIC SPI. - board-armadillo: Update all IRQ numbers to point to the GIC SPI. - pfc-r8a7740: Update all IRQ numbers of the GPIOs to point to the GIC SPI.
