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.

By setting linear_min_sel to anatop_reg->min_bit_val, we can avoid
adjust the anatop_reg->min_bit_val offset in [set|get]_voltage_sel.

With this chance we can refactor this driver to use
regulator_[get|set]_voltage_sel_regmap.

The mask used in anatop_get_voltage_sel does not match the mask used in
anatop_set_voltage_sel.
We need to do left shift anatop_reg->vol_bit_shift bits for the correct mask.

There is a name collision between 'struct platform_driver
anatop_regulator' and 'struct anatop_regulator', which causes some
section mismatch warnings like below.

WARNING: vmlinux.o(.data+0x154d4): Section mismatch in reference from the variable anatop_regulator to the function .devinit.text:anatop_regulator_probe()
The variable anatop_regulator references
the function __devinit anatop_regulator_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

Rename 'struct platform_driver anatop_regulator' to
'struct platform_driver anatop_regulator_driver' to fix the warnings.

Anatop is an integrated regulator inside i.MX6 SoC.
There are 3 digital regulators which controls PU, CORE (ARM), and SOC.
And 3 analog regulators which controls 1P1, 2P5, 3P0 (USB).
This patch adds the Anatop regulator driver.
