From: Chao Song <chao.song@linux.intel.com>

The modules currently supported by the SOF firmware use the base module
config containing the audio format for the input/output pin 0 for
initialization. But some processing modules with multiple input/output
pins require the audio formats to be sent with the init instance IPC
payload. Modules that require the base config extension will need to
indicate this in the module information in the firmware manifest.

Introduce a new struct sof_ipc4_base_module_cfg_ext which contains the
pin formats for the input and output pins. This will be appended to the
init instance IPC payload for modules that require it.
