arm64: irqflags: Fix clang build warnings
Clang complains when passing asm operands that are smaller than the
registers they are mapped to:
arch/arm64/include/asm/irqflags.h:50:10: warning: value size does not
match register size specified by the constraint and modifier
[-Wasm-operand-widths]
: "r" (GIC_PRIO_IRQON)
Fix it by casting the affected input operands to a type of the correct
size.
