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.

We had all these corrected in commit 0c8c6ba00c ("pinctrl: sunxi:
make bool drivers explicitly non-modular") but this new one recently
crept in.
The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/sunxi/Kconfig:config PINCTRL_SUN5I
drivers/pinctrl/sunxi/Kconfig: def_bool MACH_SUN5I
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, 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.

There is a stray printk call in the new sun5i pinctrl driver's probe
function.
Remove it.

The sun5i SoCs (A10s, A13, GR8) are all based on the same die fit in
different packages. Hence, the pins and functions available are just the
based on the same set, each SoC having a different subset.
Introduce a common pinctrl driver that supports multiple variants to allow
to put as much as we can in common.
