soc: qcom: cache_m4m_erp64: Use non-threaded IRQ handling 



Use non-threaded IRQ handlers for L2 and M4M error reports,
so that the error handler prints a meaningful backtrace
(including stack information prior to IRQ entry). This
improves the chances of being able to identify what the
system was doing when the error was reported.
