serial: pmac_zilog: report received breaks
pmz_status_handle() sets PMACZILOG_FLAG_BREAK from RR0, and
pmz_receive_chars() clears it on the null character that ends the
break without marking that character, then tests BRK_ABRT in RR1,
where the SCC does not set it in asynchronous mode. Breaks therefore
arrive as plain NULs: brk is never counted and BRKINT, PARMRK and SysRq
never see them.
Set BRK_ABRT in r1 for that character, as sunzilog does.
