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.

Support incoming VCONN Swap requests by accepting and turning
off/on VCONN.
Due to HW board limitations, if VCONN is being sourced from the
VBUS input we cannot support enabling VCONN while as a sink and
greater than 5V has been negotiated on VBUS. In that case, reject
the request. Add a device tree property that indicates whether
the board is configured for separate VCONN supply.

With PM autosleep enabled, the system may aggressively enter
and re-enter suspend in between calls to queue_work() and
when the state machine function gets executed, which may
at best result in numerous suspend/resume cycles and at
worse starve the PD state machine from even executing.
Fix this by calling pm_stay_awake() whenever the work is
queued and relinquish with pm_relax() when no further work
is to be done.

VDMs, especially structured ones, are almost always handled
as requests and responses. Hence it does not make sense to
allow more than one outgoing VDM at a time, so get rid of the
vdm_tx_queue list and simplify it to a single-issued packet.
Because port partners can only have one VDM request/response in
flight, also handle the case when a new structured request is
received before the previous response has been sent. In that
case we simply discard the queued message as it's now invalid.

As UFP since the policy engine only responds to the Discover
Identity command, all other commands are unrecognized and
therefore should be NAKed. Fix the handling as follows:
- Ensure the standard Discover Identity was sent using
SID of 0xFF00, otherwise it is invalid
- Don't NAK incoming Attention messages
- When sending a NAK, respond with the same SVID of the
initiating command, whether it was correct or not
- Enter Mode is not supported in general, but the NAK
should also be sent back with the same mode index
- Re-issue Discover SVIDs when more than 12 SVIDs are returned
- Clean up macro name prefixes from 'VDM' to 'SVDM' to
emphasize they are accessing structured VDM specific bits

Fix several issues which help address PD compliance testing:
- Soft reset should be issued instead of hard reset in cases
where an unexpected message is received.
- In source mode, send a Reject if the Request PDO object also
exceeds the advertised current capability. Fix the incorrect
bitmask in the PD_RDO_FIXED_CURR macro.
- Handle possibility of quick back-to-back RX messages by
flushing the sm worker to ensure the last message was fully
processed before overwriting the buffer.
- Discard PING messages as they are not applicable to Type-C.
- Respond to GET_SINK_CAP while in source mode, and vice
versa, respond to GET_SOURCE_CAP when in sink mode.
- Move pd->hard_reset=false to PE_SRC/SNK_TRANSITION_TO_DEFAULT
for consistency.
- Change default sink capabilities to advertise only 5V @ 900mA
since the policy engine will not automatically request higher
voltages. If userspace wants to request greater than 5V it should
also update the sink capabilities.
- Reset the protocol counters at the beginning of PE_SNK_STARTUP.
