Subject: [PATCH v1] drivers/pinconf.c: Remove redundant check for the existence of the member

"pin_config_set" in pinconf_ops.

In the function of registering pinctrl_dev, pinctrl_init_controller(),
a non-null check has already been performed on the members
pin_config_set and pin_config_group_set in the ops structure.
