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

           Say yes here if you want support for the ADC unit in the JZ4740 SoC.
           This driver is necessary for jz4740-battery and jz4740-hwmon driver.

+          This driver provides common support for accessing the device,
+          additional drivers must be enabled in order to use the
+          functionality of the device.
+
+          This driver can also be built as a module.  If so, the module
+          will be called tps6586x.
