In case of error, the function pinctrl_register() returns
ERR_PTR() not NULL. The NULL test in the return value check
should be replaced with IS_ERR().

Remove .owner field if calls are used which set it automatically.

The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/Kconfig:config PINCTRL_ARTPEC6
drivers/pinctrl/Kconfig: bool "Axis ARTPEC-6 pin controller driver"
...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.
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.

Add pinctrl driver support for the Axis ARTPEC-6 SoC.
There are only some pins that actually have different
functions available, but all can control bias (pull-up/-down)
and drive strength.
Code originally written by Chris Paterson.
