KVM: arm64: Rename SMC/HVC call handler to reflect reality
KVM handles SMCCC calls from virtual EL2 that use the SMC instruction
since commit bd36b1a9eb5a ("KVM: arm64: nv: Handle SMCs taken from
virtual EL2"). Thus, the function name of the handler no longer reflects
reality.
Normalize the name on SMCCC, since that's the only hypercall interface
KVM supports in the first place. No fuctional change intended.
