MAINTAINERS: adjust file entry in TEXAS INSTRUMENTS AUDIO (ASoC/HDA) DRIVERS

Commit 8167bd1c ("ASoC: dt-bindings: ti,pcm1681: Convert to dtschema")
converts ti,pcm1681.txt to ti,pcm1681.yaml, but misses to adjust the file
entry in TEXAS INSTRUMENTS AUDIO (ASoC/HDA) DRIVERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Adjust the file entry in TEXAS INSTRUMENTS AUDIO (ASoC/HDA) DRIVERS after
this conversion.
