stm32mp1: add stusb1600 support for DK1 and DK2 board
The DK1 and DK2 boards use the USB Type-C controller STUSB1600.
This patch updates:
- the device tree to add the I2C node in the DT
- the board stm32mp1 to probe this I2C device and use this controller
to check cable detection.
- the DWC2 driver to support a new dt property
"u-boot,force-b-session-valid" which forces B session and
device mode; it is a workaround because the VBUS sensing and
ID detection isn't available with stusb1600.
