[PATCH 08/19] ASoC: SOF: debug: Add SOF_DBG_DUMP_OPTIONAL flag for DSP dumping

[Peter Ujfalusi]

The new SOF_DBG_DUMP_OPTIONAL flag can be used to mark a DSP dump that
should only be printed when the SOF_DBG_PRINT_ALL_DUMPS sof_core_debug
flag is set, otherwise it should be ignored and not printed.
