Enable the freshly introduced Kconfig options whenever their matching
architecture is enabled.
Since the Kconfig symbols for these machines are going through a different
tree, keep PINCTRL_SUNXI around for the moment to avoid breaking the defconfig.
It should be removed eventually.

The way that reset is handled right now is that it is made optional for every
pinctrl driver, while actually, it isn't used at all for the main pin
controllers so far, and while it's mandatory for the A31's secondary pin
controller.
Move the reset functions out of the core and in the driver, where they can be
made mandatory.

Add one Kconfig option for each driver. This will allow to better control which
driver is enabled, instead of having either all or nothing.

Move the pin description to a driver specific to be.
This is the final step toward retiring pinctrl-sunxi-pins.h that used to define
all the pins for all the Allwinner SoCs in a single header, that would have in
turn result in having these structures in the final binary as many times as the
header was included.
We can finally remove that header, and remove all the driver part of the
pinctrl-sunxi core.

The previous code was calling of_iomap, which doesn't do any resource
management, and doesn't call request_mem_region either. Use
devm_ioremap_resource that do both.

We previously had an evergrowing (and exhaustive) list of the pins that could
be used on any Allwinner SoCs. These defines were then used by each pinctrl
driver to declare the list of functions for this pin. Since it's pretty much
all boilerplate, we can remove it just by a single macro.
