ASoC: mediatek: mt8186: set the correct string to strncmp() 

Fix Smatch static checker warning. strncmp() here only needs to compare
the first seven bytes, so in order to make the code more clear, only the
first seven bytes of the string used as the comparison are reserved.

Bug report: https://www.spinics.net/lists/alsa-devel/msg145608.html
