backends/native: Update PropTable on hotplug and remove parse callback

Browse Source 
Updating the PropTable has the side effect that the parse callback now
also gets called on hotplug but it is used to initialize data. The parse
callbacks are moved to the read_state functions which are aware if this
is an initializing call or just an update.
