Dove pinctrl uses some global config registers to control pins.
This patch requests a syscon regmap for those registers. As this
changes DT to driver requirements, fallback to a self-registered
regmap with hardcoded resources, if the corresponding syscon DT
node is missing. Also, WARN about old DT binding usage to encourage
users to update their DTBs.

Dove pinctrl also requires additional registers to control all pins.
This patch requests resources for mpp4 and pmu-mpp register ranges.

match->data is const void * where as dev.platform_data is just void *.
Add a cast to remove the const, which is causing the compiler warning:

discards 'const' qualifier from pointer target type

Dove has the exact same warning, so gets the same cast.

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,
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.

Like the spear platform, the mvebu platform has multiple files: one
core file, and then one file per SoC family. More files will be added
later, as support for mach-orion5x and mach-mv78xx0 SoCs is added to
pinctrl-mvebu. For those reasons, having a separate subdirectory,
drivers/pinctrl/mvebu/ makes sense, and it had already been suggested
by Linus Wallej when the driver was originally submitted.
