gpio: initialize descriptor SRCU structure before adding OF-based chips

Browse source

In certain situations we may end up taking the GPIO descriptor SRCU read
lock in of_gpiochip_add() before the SRCU struct is initialized. Move
the initialization before the call to of_gpiochip_add().

Fixes: be711caa87 ("gpio: add SRCU infrastructure to struct gpio_desc")
Fixes: 1f2bcb8c8c ("gpio: protect the descriptor label with SRCU")
