[PATCH 07/11] pinctrl: scmi: give no groups to pin-only functions

[Clément Le Goffic]

For a pin-only function PINCTRL_LIST_ASSOCIATIONS returns pins, but the
driver registered them as groups. Register pin-only functions without
groups.

Fixes: eb524cb651b7 ("pinctrl: Implementation of the generic scmi-pinctrl driver")
