dt-bindings: interrupt-controller: arm,gic-v3: Describe ESPI range support

GICv3.1 introduces support for new interrupt ranges, one of them being
the Extended SPI range (ESPI). The DT binding is extended to deal with
it as a new interrupt class.

The 2nd cell contains the interrupt number for the interrupt type.
SPI interrupts are in the range [0-987]. PPI interrupts are in the
