arm/arm64: KVM: Correct KVM_ARM_VCPU_INIT power off option
commit 3ad8b3de526a76fbe9466b366059e4958957b88f upstream. The implementation of KVM_ARM_VCPU_INIT is currently not doing what userspace expects, namely making sure that a vcpu which may have been turned off using PSCI is returned to its initial state, which would be powered on if userspace does not set the KVM_ARM_VCPU_POWER_OFF flag. Implement the expected functionality and clarify the ABI.
