acpi/arm64: remove unnecessary cast

DEFINE_RES_IRQ returns struct resource type, so it is
unnecessary to cast it to struct resource.

Remove the unnecessary cast to fix the following sparse warnings:

drivers/acpi/arm64/gtdt.c:355:19: sparse: warning: cast to non-scalar
drivers/acpi/arm64/gtdt.c:355:19: sparse: warning: cast from non-scalar

No functional changes intended.
