pinctrl: mediatek: Initialize variable *buf to zero 



Coverity spotted that *buf is not initialized to zero in
mtk_pctrl_dbg_show. Using uninitialized variable *buf as argument to %s
when calling seq_printf. Fix this coverity by initializing *buf as zero.

Fixes: 184d8e13 ("pinctrl: mediatek: Add support for pin configuration dump via debugfs.")
