Old pinctrl drivers will need to disable strict mode for various reasons,
among which:
- Some DT will still have a pinctrl group for each GPIO used, which will
be rejected by pin_request. While we could remove those nodes, we still
have to deal with old DTs.
- Some GPIOs on these boards need to have their pin configuration changed
(for bias or current), and there's no clear migration path
Let's disable the strict mode on those SoCs so that there's no breakage.

The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/sunxi/Kconfig:config PINCTRL_SUN9I_A80_R
drivers/pinctrl/sunxi/Kconfig: def_bool MACH_SUN9I
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

Like the previous designs, the A80 has a special pin controller for the
critical pins, like the PMIC bus.
Add a driver for this controller.

[wens: Add A80 compatible strings to bindings doc; fix pin function
names based on v1.3 datasheet; constify of_device_id table]
