Recently support for LSM6DS3 sensor using I2C address 0x6A was introduced, here support is extended to it's alternative I2C address of 0x6B.

Basic identification of TCA9555 IO Expander in introduced using the I2C address of 0x26. The device has 8 alternative addresses (0x20-0x27) and provision for all of these alternatives is not introduced here (yet?).

This PR also corrects a serial hang issue caused by USB_MODE configuration. Fixes #3566

Hope I've done everything to make this PR easy to review, let me know any issues etc.
