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.
