pinctrl: pinconf: Fix display of configs
The function pinconf_dbg_config_print() only prints the configuration of the 1st pin config in an array of pin configurations. Fix this so that all pin configurations in the array are displayed. There are a few places in the code where the pin configs are displayed and so add a helper function to display the pin configs to simplify the code.
