usb: pd: Handle PD_ALLOWED within state machine

Charger may be able to detect a legacy cable connection in which
PD is not supported however the state machine still needs to
run in order to send the EXTCON_USB notification to start the
USB controller in peripheral mode (assuming type is SDP or CDP).
Move checking of PD_ALLOWED to the state machine which can be used
to determine if moving beyond PE_SNK_STARTUP is allowed or not.

The psy_changed() callback should only queue the work when either
typec_mode or pd_allowed states have changed. Also move handling
of the in_pr_swap flag to this function by absorbing the
disconnect callback and clearing the flag when CC state indicates
it is reconnected.
