irqchip/ts4800: Add TS-4800 interrupt controller

Browse source

This commit adds support for the TS-4800 interrupt controller. This
controller is instantiated in a companion FPGA, and multiplex interrupts
for other FPGA IPs.

As this component is external to the SoC, the SoC might need to reserve
pins, so this controller is implemented as a platform driver and doesn't
use the IRQCHIP_DECLARE construct.
