[PATCH 16/19] ASoC: SOF: loader: Add support for IPC dependent post firmware boot ops

[Peter Ujfalusi]

Add support for executing IPC dependent tasks after a successful firmware
boot.

The new post_fw_boot ops can make the fw_loader query_fw_configuration
callback redundant as IPC code can handle the first boot internally.
