Servo_v4 requires the ability to have a different default state per
port. In previous devices, the assumption was that each supported port
had the same default usb pd state and power role. This CL moves the
by the default power role which in turn is derived from
CONFIG_USB_PD_DUAL_ROLE. In addiiton to moving the location, it now
uses 'port' as argument so it can be port specific if required.
PD_DEFAULT_STATE was a board.h specific config, but in practice each
instance used to date was set to PD_STATE_SNK_DISCONNECTED if
CONFIG_USB_PD_DUAL_ROLE was defined and set to
PD_STATE_SRC_DISCONNECTED otherwise.

charge_manager may request a charge current limit less than the

Depending on the battery / system state, setting a reduced charge

that argument for anything - we just silently throw it away in

This feature is inconsistent. Not all boards have such a symlink
(for a obvious reason).
This feature is fragile. It's most likely not tested and going to be
broken if not already. Developers won't like it if they have to test
two different ways to build boards before submitting patches.
This feature is not necessary. If you build EC in the standard way
(e.g. make BOARD=samus), these symlinks are not needed.
This feature is wasteful. Extra disk spaces are used and extra lines
are added to Makefile (increasing code complexity slightly).

Previously CONFIG_USB_PD_TCPM_VBUS had two uses which were independent:
- When operating as a TCPC, it indicated that the VBUS level should be
tracked (through GPIO inputs) and sent to the external TCPM when
appropriate.
- When operating as a TCPM, it indicated that the VBUS level should be
obtained by querying the TCPC.
These two independent uses have been split into
CONFIG_USB_PD_TCPC_TRACK_VBUS and CONFIG_USB_PD_VBUS_DETECT_TCPC, which
sould be more clear.
In addition, CONFIG_USB_PD_VBUS_DETECT_* CONFIGs have been added for
other means of VBUS detection.
