This board features multiple USB connectors:
 * One Type-C connector with Power Delivery and Alt. Modes;
 * One MicroUSB connector, also used for bootloader SW download;
 * One USB through the RaspberryPi-compatible pins header.

Add configuration for the MTU3 controllers providing OTG support
with role switching both on the MicroUSB port, RPi pins header,
and the Type-C port found on this board.

Moreover, add the Richtek RT1715 Type-C Power Delivery Controller
which manages current source/sink, linked to the iTE IT5205 Type-C
Alternate Mode Passive Mux, handling both mode switching between
USB (up to 3.1 Gen2 10Gbps) and DisplayPort (four lanes, DP1.4,
op to 8.1Gbps) and plug orientation switching.

All USB ports reside on different controller instances, and all of
them support host or gadget and can be configured as desired at
runtime.
