The A31 R_PIO driver depends on the reset framework in a mandatory way. Express
this by adding a depends on the reset framework in Kconfig

Fix the following configuration error:
drivers/pinctrl/sunxi/Kconfig:3:error: recursive dependency detected!
drivers/pinctrl/sunxi/Kconfig:3:	symbol PINCTRL_SUNXI is selected by PINCTRL_SUN4I_A10
drivers/pinctrl/sunxi/Kconfig:9:	symbol PINCTRL_SUN4I_A10 default value contains PINCTRL_SUNXI

Add a new intermedia PINCTRL_SUNXI_COMMON, that superseeds the PINCTRL_SUNXI
one.

We still need to keep PINCTRL_SUNXI at the moment in order to preserve
bisectability. Indeed, during that merge window, we also introduced the
MACH_SUN* symbols. Since it's going through different trees, we can't rely on
the fact that the options will be there, while ARCH_SUNXI still select
PINCTRL_SUNXI.

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.

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

This will allow to create numerous files without crippling the main pinctrl
directory.
