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.

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 essentially the same change, so they are handled in batch.
Changes are (1) use builtin_platform_driver, (2) use init.h header
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.
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 do delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

PG8, PG9 is said to be the CTS/RTS pins for UART1 according to the A23/33
datasheets. However, the function is wrongly named "uart2" in the pinctrl
driver. This patch fixes this by modifying them to be named "uart1".

In sun4/5/6/7i, all the pin function related to NAND0 controller is
named "nand0". However, in sun8i, some of the functions are named as
"nand". This patch renamed them to "nand0", for the consistency.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

The A23 uses the same pin controller as previous SoC's from Allwinner.
Add support for the pins controlled by the main PIO controller.
