pinctrl: mediatek: mt7629: fix the 2.4 GHz Wi-Fi pin mode array

Browse Source 
The wf0_2g group contains nine pins but only eight mux values.
mtk_pinmux_set_mux() indexes the mode array once for each pin, reading
past its end when configuring pin 78 (WF0_2G_HB6). This can select an
unrelated mux value or fail with -EINVAL, preventing the Wi-Fi device
from probing.

Add the missing mode 1 entry for WF0_2G_HB6.
