**  \brief EEPROM fixup code for INI values
**
** This routine provides a place to insert "fixup" code for specific devices
** that need to modify INI values based on EEPROM values, BEFORE the INI values
** are written.
** Certain registers in the INI file can only be written once without
** undesired side effects, and this provides a place for EEPROM overrides
** in these cases.
**
** This is called at attach time once.  It should not affect run time
** performance at all
**
**  \param ah       Pointer to HAL object (this)
**  \param p_eep_data Pointer to (filled in) eeprom data structure
**  \param reg      register being inspected on this call
**  \param value    value in INI file
**
**  \return Updated value for INI file.
