camera: exclude fab code from chip id check for IMX179

The chip id consists of fab code (4bit) and sensor id (12bit).
For IMX179, chip id(0x8179): fab code(0x8) + sensor id(0x179)
However, the fab code can be changed according fab location,
therefore the fab code should be excluded from chip id check.
