Robin Murphy 4deb96e35c irqchip/gicv3: Handle resource request failure consistently ...

Due to a silly oversight on my part, making the simple switch to
of_io_request_and_map() in the DT path inadvertently introduced
divergent behaviour, whereby failng to request an iomem region now
becomes fatal for DT, vs. being silently ignored for ACPI.

Refactor a bit harder, so that request errors are non-fatal in both
paths as intended, but also consistently reported as well.
