gicv2: enable configuring IRQ trigger type
This patch introduces new helper routines that allow
configuring the individual IRQs to be edge/level-triggered
via GICD_ICFGR registers. This is helpful to modify
the default configuration of the non-secure GIC SPI's, which
are all set during initialization to be level-sensitive.
