Added rk808 drivers to my and added basic Kconfig/Makefile entry for mfd driver.
chip-id of my pmic is read:
rk808 rk8090: chip id: 0x8090
looks like regulators are enabled during access from my iodomain driver :) except vccio4/5

vccio 4/5 using regulator with name SWITCH_REG1, maybe this is not registered?
