usb: typec: tcpm: allow sink (ufp) to toggle into accessory mode debug

Browse source

This patch extends the is_debug macro to cover the sink case (ufp). It
also handles the transition to access the DEBUG_ACC_ATTACHED state in
the sink case. It also handles the debounce case in which the cc
pins are not immediately valid after the plug event.
