logger: Send parsed runtime log levels to FW via debugFS 

"/sys/kernel/debug/sof/filter" file is responsible for updating
trace log levels. IPC message contain list of new trace threshold,
it is represented as single line in file where entries are separated
with ";". Single entry has form of:
"<uuid_id> <pipe_id> <comp_id> <log_level>"
