In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

As a followup to CL:3104290, give the TCPCI TRANSMIT and
RX_BUF_FRAME_TYPE types more consistent names. Most of them can be used
for receiving, not just transmitting. Fix lint errors thus revealed.

Rename tcpm_transmit_type to tcpm_sop_type to reflect that it can be
used for Rx as well. Describe it in comments. This prepares to
consolidate enum pd_msg_type into this enum.

1. Thunderbolt Mode SOP' VDO active/passive bit (B25) is
TBT_CABLE_ACTIVE or

This header file is used from quite a few files, relying on the EC
build system to find includes in the driver/tcpm directory. For Zephyr
we don't want to add that as an include.
It makes more sense for header files to be in an include directory, so
move it and fix up the users.

The CL also checks if the port is VCONN source before sending Enter USB
SOP' and SOP'' messages and requests for a vconn swap is it isn't
In case of reboot, the port sends exit Thunderbolt mode SOP' and SOP''
and skips sending exit Thunderbolt mode for SOP, since it didn't enter
Thunderbolt mode SOP prior to reboot.
Note:
1. This is only applicable when the port enters USB4 mode SOP and
Thunderbolt mode with the cable plug.
2. It is a temporary behaviour until data reset feature is in place

When chipset is transitioning to a new state or on sysjump, the EC
re-negotiates to enter an alternate mode on booting up.
This commit adds support for exiting Thunderbolt mode for SOP' and SOP''
for active cable on chipset transition and also moves all the alternate
mode exit rotines to their respective files.
It also delays deleting the SVID data until after the EXIT_MODE message
has ACKed and avoids pd_dfp_exit_mode() from changing the alternate
mode's internal states.
This commit also makes sure that the mux is set to safe state before
exiting the alternate mode and it is reconfigured according to the
port's current data role on receiving ACK/NAK from the cable/port
partner.

Order of Enter Mode: SOP', SOP''(if supported), SOP
Order of Exit Mode: SOP, SOP''(if supported), SOP'
Entry flow start from TBT_START, state changes to TBT_ACTIVE if succeed;
changes to TBT_INACTIVE if fail.
Handling of NAK
If any enter mode SOP* is NAK'ed, exit modes of all SOP* and retry enter.
If any enter mode in retry is NAK'ed again, will exit modes of all SOP*,
TBT entry failed.
Special case:
Exit in TBT_ACTIVE: start from TBT_ACTIVE, exit all modes of SOP*, then
chagne state to TBT_INACTIVE.

When chipset is transitioning to a new state or on sysjump, the SOC
re-negotiates to enter an alternate mode on booting up.
This commit:
1. Adds a common DPM function to check for all the active alternate modes
one at a time, construct the VDM and send the DPM request to exit the
mode.
2. Marks thunderbolt mode as inactive in DFP's thunderbolt mode exit
function.

Create a separate module for representing Thunderbolt mode which decides
whether and how we can enter into Thunderbolt alternate mode.
Modify the Device Policy Manger (usb_pd_dpm.c) to first check if the
port partner and cable is a Thunderbolt Compatible. If not, continue the
rest of the PD flow undisturbed.
