mfd: Support for ROHM BD71815 PMIC core

Browse Source 
Add core support for ROHM BD71815 Power Management IC.

The IC integrates regulators, a battery charger with a coulomb counter,
a real-time clock (RTC), clock gate and general-purpose outputs (GPO).

Select this option to get support for the ROHM BD71828 Power
Management IC. BD71828GW is a single-chip power management IC for
battery-powered portable devices. The IC integrates 7 buck
converters, 7 LDOs, and a 1500 mA single-cell linear charger.
Also included is a Coulomb counter, a real-time clock (RTC), and
a 32.768 kHz clock gate.
Select this option to get support for the ROHM BD71828 and BD71815
Power Management ICs. BD71828GW and BD71815AGW are single-chip power
management ICs mainly for battery-powered portable devices.
The BD71828 integrates 7 buck converters and 7 LDOs. The BD71815
has 5 bucks, 7 LDOs, and a boost for driving LEDs. Both ICs provide
also a single-cell linear charger, a Coulomb counter, a real-time
clock (RTC), GPIOs and a 32.768 kHz clock gate.
