coresight: Add support to get static id for system trace sources

Dynamic trace id was introduced in coresight subsystem, so trace id is
allocated dynamically. However, some hardware ATB source has static trace
id and it cannot be changed via software programming. For such source,
it can call coresight_get_static_trace_id to get the fixed trace id from
device node and pass id to coresight_trace_id_get_static_system_id to
reserve the id.
