KVM: arm64: Factor out reusable vCPU reset helpers

Browse source

Pull the reusable pieces out of kvm_reset_vcpu(): expose the reset
PSTATE values in kvm_arm.h, and split the core register reset and the
PSCI-driven reset into kvm_reset_vcpu_core() and kvm_reset_vcpu_psci().
A follow-up series reuses these to reset protected vCPUs at EL2.

No functional change intended.
