[PATCH 1/9] pinctrl: as3722: make it explicitly non-modular

[Paul Gortmaker <paul.gortmaker@xxxxxxxxxxxxx>]

The Kconfig currently controlling compilation of this code is:

config PINCTRL_AS3722
        bool "Pinctrl and GPIO driver for ams AS3722 PMIC"

...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_ALIAS and MODULE_DEVICE_TABLE are a no-op for
non-modular code and hence both are removed.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
