Victor Sun a5158e2c16 HV: refine reset_vcpu api ...

The patch abstract a vcpu_reset_internal() api for internal usage, the
function would not touch any vcpu state transition and just do vcpu reset
processing. It will be called by create_vcpu() and reset_vcpu().

The reset_vcpu() will act as a public api and should be called
only when vcpu receive INIT or vm reset/resume from S3. It should not be
called when do shutdown_vm() or hcall_sos_offline_cpu(), so the patch remove
reset_vcpu() in shutdown_vm() and hcall_sos_offline_cpu().

The patch also introduced reset_mode enum so that vcpu and vlapic could do
different context operation according to different reset mode;
