mfd: Set tps6586x bits if new value is different from the old one
It does not make sense to write new value only when all the bit_mask
bits are zero.
We need to write new value if the bit mask fields of new value is
not equal to old value.

mfd: Fix tps6586x GPIO value setting
In the current code, every time we set a TPS6586x GPIO pin,
the tps6586x_gpio_set function is resetting all other GPIO pins.
We need to update the right GPIOxOUT bit of the GPIOSET2 register instead
of overriding the full value.
Tested by setting sequentially GPIO2 and GPIO3 and verifying the
pins voltage.

mfd: Remove tps6586x device ID check
... and convert it to a dev_info print at probe time.
There are many variants of this chip with different values of VERSIONCRC.
The set of values is large, and not useful to enumerate. All are SW
compatible. The difference lies in default settings of the various power
rails, and other similar differences. The driver, or clients of the
driver, shouldn't be affected by this, since all rails should be
programmed into the desired state in all cases for correct operation.

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
