Currently i2c_of_match_device_sysfs() is used by i2c_of_match_device().
Convert this to non-static function for finding match data for the I2C
sysfs interface using i2c_device_get_match_data() for code reuse.
While at it, fix the below issues:
1) Replace 'of_device_id*'->'of_device_id *' in function definition.
2) Fix the alignment in the function definition.
3) Change the struct i2c_client parameter as const to avoid overriding
the client pointer.
