ASoC: mediatek: mt8192: refactor for I2S3 DAI link of speaker

As part of the refactoring to allow the same machine driver to be used for
the rt1015(p) and rt5682(s) codecs on the MT8192 platform, parse the
rt1015(p) codecs from the speaker-codecs property in the devicetree and
wire them to the I2S3 backend, instead of hardcoding the links and
selecting through the compatible.
