fuelgauge: max17042: fix i2c read issue which causes infinity loop.
Issues:
- reading i2c data by passing u16 pointer causes errors in read data.
- max17042 status register fields have not only Power On Reset meaning
so using proper mask is required.
Changes:
- read i2c data to type u32 instead of u16 - avoids buffer overflow
- compare FG status register using mask not just one bit value
- add checking return value to functions fg read/write
- add model lock and model check count
- add debug msg
