pinctrl.txt: Remove outdated information

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.

@ -274,15 +274,6 @@ configuration in the pin controller ops like this::
.confops = &foo_pconf_ops,
};
Since some controllers have special logic for handling entire groups of pins
they can exploit the special whole-group pin control function. The
pin_config_group_set() callback is allowed to return the error code -EAGAIN,
for groups it does not want to handle, or if it just wants to do some
group-level handling and then fall through to iterate over all pins, in which
case each individual pin will be treated by separate pin_config_set() calls as
well.
