This board is a relatively inexpensive development kit for USB-PD
controllers, using an UPD301C controller.
This Zephyr config includes support for:
* UART (present on he debug header of the board), tested with the
hello_world sample application;
* the one standalone LED (CAP_MIS), tested with the blinky sample
application;
* the rotary encoder (PDO_SEL), via ADC, tested with the adc sample
application;
* the current sense amplifier (I_SENSE), currently untested;
* the SPI bus, connected internally in the UPD301C to the UPD350;
* the I2C bus, exposed on the debug header, currently untested.
Note that the drivers.uart.async_api.rtt has to be disabled, as it is
for other m0 boards with no dma or it fails to build.
