x86/paravirt: Replace io_delay() hook with a bool

Browse source 
The io_delay() paravirt hook is in no way performance critical and all users
setting it to a different function than native_io_delay() are using an empty
function as replacement.

Allow replacing the hook with a bool indicating whether native_io_delay()
should be called.
