pinctrl: palmas: do not abort pin configuration for BIAS_DEFAULT
Recent movement of all configurations of pin in the single call of pin_config_set(), it is aborting configuration if BIAS_PULL_PIN_DEFAULT is selected as return of configuration. The original idea was to just avoid any update on register for pull up/down configuration if this option is selected. Fixing this by just bypassing any register update for BIAS_PULL_PIN_DEFAULT and continuing the remaining configuration.
