irqchip/gicv2m: Miscellaneous fixes for v2m resources and SPI ranges
This patch contain fixes for v2m resources and SPI ranges:
* Fix off-by-one error when set up v2m resource end range in
gicv2m_acpi_init().
* Fix the off-by-one print error for SPI range.
* Use %pR to properly print resource range information.
Both ACPI and DT should now print:
GICv2m: range[mem 0xe1180000-0xe1180fff], SPI[64:319]
