arm/arm64: smccc: Make function identifiers an unsigned quantity
Function identifiers are a 32bit, unsigned quantity. But we never
tell so to the compiler, resulting in the following:
4ac: b26187e0 mov x0, #0xffffffff80000001
We thus rely on the firmware narrowing it for us, which is not
always a reasonable expectation.
