fix(gicv3): map generic interrupt type to GICv3 group
The generic interrupt controller identifies an interrupt based on its
type whereas the GIC uses the notion of groups to identify an
interrupt.
Currently, they are used interchangeably in GICv3 driver. It did not
cause any functional issues since the matching type and group had the
same value for corresponding macros. This patch makes the necessary
fixes.
The generic interrupt controller APIs, such as
plat_ic_set_interrupt_type map interrupt type to interrupt group
supported by the GICv3 IP. Similarly, other generic interrupt
controller APIs map interrupt group to interrupt type as needed.
This patch also changes the name of the helper functions to use group
rather than type for handling interrupts.
