rdn1edgex2: add patch to improve the reliability of cross chip events

RD-N1-Edge-Dual FVP has known reliability issue with stlr instruction
while sending events across the chip through the CCIX link. This can be
fixed by explicitly sending event using sev instruction after strl. Add
this patch as part of the pre tf build step.
