This adds more complete handling of VDMs and registration of
partner alternate modes, and introduces callbacks for
alternate mode operations.
Only DFP role is supported for now.

This commit adds code to handle requesting of PPS APDOs. Switching
between standard PDOs and APDOs, and re-requesting an APDO to
modify operating voltage/current will be triggered by an
external call into TCPM.

Since there is no user of max_snk_*, so we can remove them from tcpm.

Remove the unused (not implemented anywhere) tcpc_mux_dev abstraction
and replace it with calling the new typec_set_orientation,
usb_role_switch_set and typec_set_mode functions.

Setting the mux to MUX_NONE and the switch to USB_SWITCH_DISCONNECT when
the data-role is device is not correct. Plenty of devices support
operating as USB device through a (separate) USB device controller.
We really need 2 different versions of USB_SWITCH_CONNECT,
USB_SWITCH_CONNECT_HOST and USB_SWITCH_DEVICE. Rather then modifying the
tcpc_usb_switch enum for this, simply remove it and switch to the
usb_role enum which provides exactly this, this will save use needing to
convert betweent the 2 enums when calling an usb-role-switch driver later.
Besides switching to the usb_role type, this commit also actually sets the
mux to TYPEC_MUX_USB and the switch to USB_ROLE_DEVICE instead of setting
both to none when the data-role is device.
This commit also makes tcpm_reset_port() call tcpm_mux_set(port,
TYPEC_MUX_NONE, USB_ROLE_NONE) so that the mux and switch
do _not_ stay in their last mode after a detach.

USB Type-C specification v1.2 separated the power and data
roles more clearly. Dual-Role-Data term was introduced, and
the meaning of DRP was changed from "Dual-Role-Port" to
"Dual-Role-Power".
In order to allow the port drivers to describe the
capabilities of the ports more clearly according to the
newest specifications, introducing separate definitions for
the data roles.

The source and sink caps should follow the following rules.
This patch validates whether the src_caps/snk_caps adheres
to it.
6.4.1 Capabilities Message
A Capabilities message (Source Capabilities message or Sink
Capabilities message) shall have at least one Power
Data Object for vSafe5V. The Capabilities message shall also
contain the sending Port’s information followed by up to
6 additional Power Data Objects. Power Data Objects in a
Capabilities message shall be sent in the following order:
1. The vSafe5V Fixed Supply Object shall always be the first object.
2. The remaining Fixed Supply Objects, if present, shall be sent
in voltage order; lowest to highest.
3. The Battery Supply Objects, if present shall be sent in Minimum
Voltage order; lowest to highest.
4. The Variable Supply (non-battery) Objects, if present, shall be
sent in Minimum Voltage order; lowest to highest.
Errors in source/sink_caps of the local port will prevent
the port registration. Whereas, errors in source caps of partner
device would only log them.
