ice: add TTY for GNSS module for E810T device
Add a new ice_gnss.c file for holding the basic GNSS module functions.
If the device supports GNSS module, call the new ice_gnss_init and
ice_gnss_release functions where appropriate.
Implement basic functionality for reading the data from GNSS module
using TTY device.
Add I2C read AQ command. It is now required for controlling the external
physical connectors via external I2C port expander on E810-T adapters.
Future changes will introduce write functionality.
