Revert "Add I2C mutex for lookup table write function"

This reverts commit f05e687e90935dd2b5086dca762e4f757af80175.

Adding a lock call around i2c_eeprom_master_write creates a
deadlock as i2c_eeprom_master_write already takes the I2C
mutex. The correct fix would be to move the lock call out of
i2c_eeprom_master_write and adapt all callers.
Rebuild to pickup fix from brickletlib to avoid sending threshold callback twice
