[ALSA] hda-codec - alc268 input_mux should be a selector instead of mixer 

According to the [0003659], the node 0x23,0x24 is a selector.
I checked the alc268 spec on the REALTEK website and it showed that they
were selectors indeed.
However, current code implement the alc268 input_mux in a mixer way.
