This patch adds a new driver for Richtek RT5033 driver.
RT5033 is a Multifunction device which includes battery charger, fuel gauge,
flash LED current source, LDO and synchronous Buck converter. It is interfaced
to host controller using I2C interface.

Changes in v6
- Fix white space issue in mfd cell struct.

Changes in v5
- Change possible built as a module.
- Revise rt5033_dev mfd cell entry.
- Fix incorrect typo.
- Add module alias.

Changes in v4
- none.

Changes in v3
- Correct sentence errors.
- Add author information the top of each drivers.
- Remove unnecessary pre-initialise, struct member(rt5033->i2c) and blink.
- Change some return check.
- Use bool and of_match_ptr().

Changes in v2
- Remove volatile_reg callback. Because this driver not in use regmap cache.
- Revmoe unnecessary subnode of_compatible.
- Add define for set_high impedance mode of charger.
