[Minor_Improvement] Add I2C multi sensor single bus init and de-init functtions

[elsalahy]

Summary:

Sensor I2C init functions can call BSP init, or the BSP init can be called alone.
Need to add a handling for the senors init functions in case multiple sensors are on the same bus, in order to ensure only one BSP init is called.

Why do we need this?

To avoid un-needed re-iinit of the bus and have a coherant implementation.

What is already there? What do you see now?

Template init of the sensors.

What is missing? What do you want to see?

Flags, function checks, and harmonized implementation.

How do you propose to implement this?

• Add Flag if the bus is initialized already,
• Pass the I2C handler as a reference instead of using extern.
• Handle multi-sensor bus init functions checks and returns.

Environment:

Baremetal.

Acceptance Criteria:

• Should not affect sensors functionality in any way.
• Basic app must compile and run smothly.

What can you do yourself and what do you need help with?
