Detailed Description

HAL binding of the expansion (Qwiic) devices on I2C1.

Builds the bus descriptors of the portable drivers (vl53l1x, flow_bridge) on top of the STM32 HAL. Every transaction takes the I2C lock of imu_i2c.c (priority inheritance): on the bench the IMU shares the bus; on the ACwing FC rev A the IMU is on SPI and the lock is uncontended.
