irqchip: keystone: Add irq controller ip driver
On Keystone SOCs, DSP cores can send interrupts to ARM
host using the IRQ controller IP. It provides 28 IRQ
signals to ARM. The IRQ handler running on HOST OS can
identify DSP signal source by analyzing SRCCx bits in
IPCARx registers. This is one of the component used by
the IPC mechanism used on Keystone SOCs.
