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.

It's a minor issue, but I think it deserves a patch to make
the code cleaner,
