Minor cleanup of OTG timer handling:
* unify decls for OTG time constants, in the core header
* set up and use that timer in a more normal way
* move to the driver struct, so it's usable outside core
And tighten use and setup of T(a_wait_bcon) so that if it's used,
it's always valid. (If that timer expires, the A-device will
stop powering VBUS. For non-OTG systems, that will be a surprise.)
No behavioral changes, other than more consistency when applying
that core HNP timeout.
