irqchip/gicv3: Add a iort_pmsi_get_dev_id() prototype

iort_pmsi_get_dev_id() has a __weak definition in the driver, and
an override in arm64 specific code, but the declaration is conditional
and not always seen when the copy in the driver gets built:

drivers/irqchip/irq-gic-v3-its-platform-msi.c:41:12: error: no previous prototype for 'iort_pmsi_get_dev_id' [-Werror=missing-prototypes]

Move the existing declaration out of the #ifdef block to ensure
it can be seen in all configurations.
