CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

set_current_limit
Selecting the minimal value is only true for voltage regulators.
For current regulators the maximum in the given range should be
selected instead.
This issue was reported by Heiko Stuebner for gpio-regulator driver [1],
and the conclusion is to select the max current for current regulators [2].

[2] https://lkml.org/lkml/2012/8/6/183
This patch also ensures da9055_buck_set_current_limit return -EINVAL when the
supported current limit does not meet the request range.

offset
This patch implements map_voltage and list_voltage callbacks to properly handle
the case voltage range that doesn't start with 0 offset.
Now we adjust the selector in map_voltage() before calling set_voltage_sel().
And return 0 in list_voltage() for invalid selectors.
With above change, we can remove da9055_regulator_set_voltage_bits function.
One tricky part is that we need adding voffset to n_voltages.
Although for the cases "selector < voffset" are invalid, we need add voffset to
n_voltage so regulator_list_voltage() won't fail while checking the boundary for
selector before calling list_voltage callback.

Check pdata->gpio_rsel && pdata->gpio_rsel[id] for the case GPI pin is muxed
with regulator to select the regulator register set A/B for voltage ramping.

This is the Regulator patch for the DA9055 PMIC and has got dependency on
the DA9055 MFD core.
This patch support all of the DA9055 regulators. The output voltages are
fully programmable through I2C interface only. The platform data with regulation
constraints is passed down from the board to the regulator.
This patch is functionaly tested on SMDK6410 board. DA9055 Evaluation board
was connected to the SMDK6410 board.
