Andrew Davis 5668db72b7 feat(ti): set snoop-delayed exclusive handling on A72 cores
Snoop requests should not be responded to during atomic operations. This
can be handled by the interconnect using its global monitor or by the
core's SCU delaying to check for the corresponding atomic monitor state.

TI SoCs take the second approach. Set the snoop-delayed exclusive handling
bit to inform the core it needs to delay responses to perform this check.

As J784s4 is currently the only SoC with multiple A72 clusters, limit
this delay to only that device.
