ASoC: SOF: loader: Remove snd_sof_parse_module_memcpy() as it is not used

Browse source 
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.
