Revert "gpio: Access `gpio_bus_type` in gpiochip_setup_dev()"
This reverts commit cc11f4ef666fbca02c8a2f11d0184d57e6b75579.
Commit cc11f4ef666f ("gpio: Access `gpio_bus_type` in
gpiochip_setup_dev()") moved the bus type assignment from
gpiochip_add_data_with_key() to gpiochip_setup_dev().
This change introduced a bug where dev_printk() and friends might access
the bus name after gpiochip_add_data_with_key() but before
gpiochip_setup_dev() has run. In this window, the bus type is not yet
initialized, leading to empty bus names in logs.
Move the bus type assignment back to gpiochip_add_data_with_key() to
ensure the bus name is available before any potential users like
dev_printk().
