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

In the case of goto err2, what we want is to call
platform_device_del() instead of platform_device_unregister().
Otherwise, we call platform_device_put() twice.

The WM8321 is a PMIC for low power, high performance applications. From a
software point of view the device is identical to the WM8320, all the
differences between the two devices are visible only in hardware.
