Subject: [PATCH 1/5] mfd: rt5033: Add Richtek RT5033 driver core.

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.
