pinctrl: at91-pio4: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/Kconfig:config PINCTRL_AT91PIO4
drivers/pinctrl/Kconfig: bool "AT91 PIO4 pinctrl 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.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
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.
