get_el_str() was implemented under ENABLE_BACKTRACE macro but being used at generic places too, this causes multiple definition of this function. Remove duplicate definition of this function and move it out of backtrace scope. Also, this patch fixes a small bug where in default case S-EL1 is returned which ideally should be EL1, as there is no notion of security state in EL string.
