This series adds support for STMicroelectronics STUSB160x Type-C port
controllers [1].
STUSB160x driver requires to get power operation mode via device tree,
that's why this series also adds the optional DT property power-opmode
for usb-c-connector to select the power operation mode capability and
a function to convert the power operation mode string into power
operation mode value.
This driver has been tested on stm32mp157c-dk2 [2], which has a Type-C
connector managed by STUSB1600, and connected to USB OTG controller.
