Subject: [PATCH] ASoC: SOF: loader: Remove snd_sof_parse_module_memcpy() as it is not used
Git-commit: 910bd536d3f72d9c39e5ec08e946c11f9bcdc532
Patch-mainline: v5.19-rc1
References: jsc#PED-850

The snd_sof_parse_module_memcpy() is no longer used and we have the
implementation of it in ipc3-loader.c which is a default mode to load
module(s) with IPC3 if the snd_sof_load_firmware_memcpy() is used for
loading the firmware.
