The code in the example does not build for a few trivial errors: type
mismatch in callback, missing semicolon. Fix them to help newcomers using
the example as a starting point.

Returning -EAGAIN is no longer supported by pin_config_group_set()
since ad42fc6c84 ("pinctrl: rip out the direct pinconf API")
Remove the relevant section from the documentation.

The pinctrl_request_gpio() and pinctrl_free_gpio() break the nice
namespacing in the other cross-calls like pinctrl_gpio_foo().
Just rename them and all references so we have one namespace
with all cross-calls under pinctrl_gpio_*().

As pinctrl describes a feature from drivers/base, place it at
the right book.
