This change adds a ccd console command to control the usb endpoints.
The uart console command is moved into this command so 'ccd uart
[enable|disable]' controls the AP and EC TX signals instead of the
'uart' console command. CCD can be enabled using 'ccd enable'. This
switches the PHY used by the USB controller to be the external PHY.
Changing the PHY exposes the cr50, AP, and EC consoles as well as the
upgrading mechanisms for the AP, EC and cr50. The AP and EC consoles
will be read only until 'ccd uart enable' is called. Cr50 can be updated
using the usb upgrade endpoint. The EC and AP can be updated using the
USB SPI endpoint.
When CCD is disabled the usb controller will switch to using the AP PHY.
None of the endpoints will be visible to the host.
The USB SPI endpoint can be used to flash the EC or AP using
'flashrom -p raiden_debug_spi:target=[AP|EC]'. If CCD is not enabled
running flashrom using the raiden_debug_spi programmer will fail. Cr50
will not forward the commands to the external AP or EC ROM, so flashrom
will not be able to find the chip.
The UART TX signals are now controlled by the 'ccd uart' console
command instead of the 'uart' console command. The UART TX is enabled
separately from CCD, because we want to be able to enable CCD while
servo is connected, and having the cr50 UART TX pins wired directly to
the Servo TX lines could damage both devices. The AP and EC consoles
are be read only until 'ccd uart enable' is called. 'ccd uart disable'
disconnects the AP and EC TX pins from the UART peripheral.
When RDD becomes reliable on cr50, ccd_set_mode will select the PHY
being used by the g chip USB controller.

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

This change creates CONFIG_CMD_GPIO_EXTENDED

worthwhile to add this for all, or not.
This change is also necessary also for servo micro JTAG and PD

TEST=Manual on lars, determine two EC versions that have enough
differences so that replacing one image with the other will
require all or most of the flash pages to be updated. Alternate
between flashing the two images with flashrom using a script.
Atleast 1000 iterations should pass.

The channel enum and string name array were out of sync (when
CONFIG_EXTENSION_COMMAND is defined). This was caused by the two lists
being specified separately. I argue that this is a good reason to merge
the lists into a separate X-Macro include file.
