mfd: Add TPS6586x driver
Add mfd core driver for TPS6586x PMICs family.
The driver provides I/O access for the sub-device drivers and performs
regstration of the sub-devices based on the platform requirements.
In addition it implements GPIOlib interface for the chip GPIOs.
TODO:
- add interrupt support
- add platform data for PWM, backlight leds and charger
