Subject: [PATCH V2] irqchip/irq-csky-mpintc: Fixup mask/unmask un-implementation

From: Guo Ren <guoren@...ux.alibaba.com>

The mask/unmask must be implemented, and enable/disable supplement
them if the HW requires something different at startup time. When
irq source is disabled by mask, mpintc could complete irq normally.

So just replace the with mask/unmask function.
