pinctrl: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

pinctrl: spear: make bool drivers explicitly non-modular

None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only. All
drivers get the exact same change, so they are handled in batch.

Changes are (1) use init.h header in place of module.h header,
(2) delete module_exit related code, (3) delete MODULE_DEVICE_TABLE,
and (4) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.

None of these drivers were using module_init() so we don't have to
worry about the init ordering getting changed with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

Drivers: pinctrl: remove __dev* attributes.

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.

pinctrl: SPEAr1310: Separate out pci pins from pcie_sata pin group

SPEAr1310 has separate PCI and PCIe implementations which are not muxed with
each other. Presently they have been implemented as muxed together with SATA and
are represented wrongly in the software.

In reality only PCIe and SATA implementations are muxed with each other. This
patch separates out pci pins creating a new pingroup and function for pci.
