It's safe to call regulator_unregister() with NULL, thus remove the NULL test
before regulator_unregister() calls.

All regulators have ascendant voltage list in this driver.
Use regulator_map_voltage_ascend for them.

CONFIG_HOTPLUG is going away as an option so __devinit is no longer

This patch refactors the code to get rid of the fixed_ilimsel and FIXED_ILIMSEL
flag usage, and convert all the fixed ilimsel to table based (with one entry in
the table).
We can differentiate fixed ilimsel by checking info->n_ilimsels == 1,
thus FIXED_ILIMSEL flag can be removed.
This change makes the logic of the code simpler as all the ilimsels are table
based now.

This patch adds fixed_5000000_voltage table for fixed voltage,
so we can convert regulator_ops to regulator_list_voltage_table.
We can differentiate fixed voltage by checking rdev->desc->n_voltages == 1,
thus remove the FIXED_VOLTAGE flag usage.

Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.
The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

Unusual to see a regulator driver not using subsys_initcall() but the
deferred probe support should make this viable.

Pull regulator updates for 3.4 from Mark Brown:
"This has been a fairly quiet release from a regulator point of view,
the only real framework features added were devm support and a
convenience helper for setting up fixed voltage regulators.
We also added a couple of drivers (but will drop the BQ240022 driver
via the arm-soc tree as it's been replaced by the more generic
gpio-regulator driver) and Axel Lin continued his relentless and
generally awesome stream of fixes and cleanups."

With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.

Fix section mismatch that is caused by init code calling exit code:
pmic_remove() cannot be marked as __devexit.
WARNING: drivers/regulator/tps6524x-regulator.o(.devinit.text+0x205): Section mismatch in reference from the function pmic_probe() to the function .devexit.text:pmic_remove()
The function __devinit pmic_probe() references
a function __devexit pmic_remove().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
pmic_remove() so it may be used outside an exit section.
