irqchip: add C-SKY APB bus interrupt controller
The driver is for C-SKY APB bus interrupt controller. It's a simple
interrupt controller which use pending reg to detect the irq and use
enable/disable reg to mask/unmask interrupt sources.
A lot of SOCs based on C-SKY CPU use the interrupt controller as root
controller.
