ArmPkg/Include: fix usage of wrong macro in ArmGicv3Dxe

To get a SPI_MAX_INTID, interrupt controller type Register
should be masked with ARM_GIC_ICDICTR_GET_SPI_RANGE.
However, since ARM_GIC_ICDICTR_SPI_RANGE_TO_MAX_INTID macro
uses ARM_GIC_ICDICTR_GET_EXT_SPI_RANGE mask,
it returns wrong SPI_MAX_INITID.

This makes a failure of loading GenericWatchDog in FVP RevC model.
