TF-mini i2c port support

[dfordequan]

Describe problem solved by the proposed feature

TF mini is a nice range finder sensor that works in outdoors, and it supports both UART and I2C interference. However, PX4 can only work with UART port with TFmini. The I2C driver is missing. That's a pity for controllers like 6c mini that doesn't gave many serial ports.

Describe your preferred solution

Install the TFmini i2c driver in the firmware.

Describe possible alternatives

Not sure

I don't have one of these modules, but if anyone has access and is interested I could help you get the driver structure in place fairly quickly.

Hi @dagar thank you for your response! I have the sensor and was trying to start with the driver. But I found out that even if I plugged in the i2c properly (cable, pins are all fine), the i2c bus scan can't detect it. Do you know any potential possibilities that might cause that? like a blacklist or something that blocks it.
