irqchip: vic: Parse interrupt and resume masks from device tree
This patch extends vic_of_init to parse valid interrupt sources and resume sources masks from device tree. If mask values are not specified in device tree, all sources are assumed to be valid, as before this patch.

Optional properties:
- interrupts : Interrupt source for parent controllers if the VIC is nested.
+- valid-mask : A one cell big bit mask of valid interrupt sources. Each bit
