musb: make initial HNP roleswitch work (v2)
Minor HNP bugfixes, so the initial role switch works:
- A-Device:
* disconnect-during-suspend enters A_PERIPHERAL state
* kill OTG timer after reset as A_PERIPHERAL ...
* ... and also pass that reset to the gadget
* once HNP succeeds, clear the "ignore_disconnect" flag
* from A_PERIPHERAL, disconnect transitions to A_WAIT_BCON
- B-Device:
* kill OTG timer on entry to B_HOST state (HNP succeeded)
* once HNP succeeds, clear "ignore_disconnect" flag
* kick the root hub only _after_ the state is adjusted
Other state transitions are left alone. Notably, exit paths from
the "roles have switched" state ... A_PERIPHERAL handling of that
stays seriously broken.
