hyperv: SControl is optional to enable SynIc
SynIc can be enabled regardless of the SControl mechanisim which can register a GSI for a given SintRoute. This behaviour can achived by setting enabling SIMP and then the guest will poll on the message slot. Once there is another message pending the host will set the message slot with the pending flag. When the guest polls from the message slot, in case the pending flag is set it will write to the HV_X64_MSR_EOM indicating it has cleared the slot and we can try and push our message again.
