ASoC: mediatek: Commonize ADDA rate transform functions and enums

Both the enumerations for UL/DL rates, delay data and the functions
adda_{dl,ul}_rate_transform were duplicated for each MediaTek SoC
dai-adda driver: move the common bits to a new mtk-dai-adda-common
file and its header.
While at it, also add the "mtk_" prefix to the exported functions.
