media: i2c: update ar0234 EEPROM data structure

Browse Source 
- Integrate calibration data structure from
  Leopard Imaging hawk driver into NVIDIA
  hawk driver
- Rearrange EEPROM calibration data structure to
  maintain backward compatibility with HAWK, OWL
  modules with EEPROMs programmed using earlier
  calibration data structure
- Use separate structures for tracking imu noise
  parameters and place it after the module
  serial number.
- Change module serial number length used for
  reading the serial number from EEPROM data
