Light Hsieh 184d8e13f9 pinctrl: mediatek: Add support for pin configuration dump via debugfs.
Add support for pin configuration dump via catting
/sys/kernel/debug/pinctrl/$platform_dependent_path/pinconf-pins.
pinctrl framework had already support such dump. This patch implement the
operation function pointer to fullfill this dump.
