ASoC: mediatek: mt8192: support rt1015p_rt5682s

Add support for using the rt5682s codec together with rt1015p on
mt8192-mt6359 machines. All configurations are shared with the rt5682
codec variant, so simply select the SND_SOC_RT5682S config to ensure the
codec is present and set the correct card name. The codec will be linked
to by pointing to it in the headset-codec property in the devicetree.

While at it, also create macros for the names of the different codec
variants supported by this driver, as well as rename occurrences of
rt1015p_rt5682 to rt1015p_rt5682x, since they are shared between rt5682
and rt5682s.
