Add topology parsing and media-format programming for Audio IF source and sink modules. Add the Audio IF module IDs, the required topology tokens, and a dedicated topology loader that stores the parsed interface configuration in the AudioReach module state. Also add the Audio IF media-format path that sends the interface configuration, hardware endpoint media format, and frame-duration parameters for Audio IF modules. This keeps the serial-interface configuration topology-driven while still allowing the machine driver to provide runtime slot and media format settings. The same Audio IF path can then be reused for TDM, PCM, and I2S style backends. The new UAPI tokens (AR_TKN_U16_MODULE_SYNC_SRC=262 through AR_TKN_U8_MODULE_INV_EXT_BIT_CLK=276) are added, together with the value defines used by the sync source, sync mode, data delay, interface mode, bit clock type, and polarity tokens. MODULE_ID_AUDIO_IF_SINK (0x0700117C) and MODULE_ID_AUDIO_IF_SOURCE (0x0700117D) are introduced in this patch. This Module is validated on Hawi and Shikra platforms.
