Subject: [PATCH] pinctrl.txt: Remove outdated information

Returning -EAGAIN is no longer supported by pin_config_group_set()
since ad42fc6c8479 ("pinctrl: rip out the direct pinconf API")

Remove the relevant section from the documentation.

-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.
