HNP polling is a mechanism which allows the OTG device currently acting as host
to determine when the other attached OTG device wishes to take the host role.
When an OTG host, which supports HNP, is connected to an OTG peripheral which
also supports HNP it shall poll the peripheral regularly to determine whether
it requires a role-swap and grant this at the earliest opportunity.
