Changes in v2:
- Added chained_irq_{enter,exit} in interrupt handler.

drivers/irqchip/irq-ts4800.c
This is an interrupt-controller implemented in an FPGA, to multiplex
interrupts generated from other IPs. The FPGA usually uses a GPIO as a
parent interrupt controller to notify that one of the multiplexed
interrupts has triggered.
