sof: replace log calls with zephyr logging api

The log context in zephyr is per file or module.

To use zephyr logging api, LOG_MODULE_REGISTER is used
to register a log context, LOG_MODULE_DECLARE is used
to refer to the registered context.

For function in header file, LOG_MODULE_DECLARE should
be used within that function to avoid context collapse,
a condition one source file have multiple context
registered or declared.
