Subject: [PATCH] gpio: aggregator: restore the set_config operation

Restore the set_config operation, as it was lost during the refactoring of
the gpio-aggregator driver while creating the gpio forwarder library.

Fixes: b31c68fd851e7 ("gpio: aggregator: handle runtime registration of gpio_desc in gpiochip_fwd")
Reported-by: kernel test robot <oliver.sang@...el.com>
Closes: https://lore.kernel.org/oe-lkp/202509281206.a7334ae8-lkp@intel.com
