[PATCH 3/5] arm/arm64: KVM: Clarify KVM_ARM_VCPU_INIT ABI

[Christoffer Dall]

It is not clear that this ioctl can be called multiple times for a given
vcpu.  Userspace already does this, so clarify the ABI.

 Possible features:
 	- KVM_ARM_VCPU_POWER_OFF: Starts the CPU in a power-off state.
 	  Depends on KVM_CAP_ARM_PSCI.  If not set, the CPU will be powered on
