gpio: s32: don't run callbacks in some callbacks

The functions "siul2_gpio_dir_in" and "siul2_gpio_free" have been
registered to be callbacks as "gc->direction_input" and "gc->free".
When the callbacks "irq_chip->irq_set_type/irq_unmask/irq_mask"
are called, the caller should guarantee that it will call
gc->direction_input and gc->free explicitly instead of counting on
irq_set_type/irq_unmask/irq_mask to do this. So let's remove calling
of the callbacks from callbacks to avoid calling them multiple times.

This patch fixes the calltrace as below:
