arm64: dts: juno: Enable coresight tmc scatter gather in ETR
We do not enable scatter-gather mode in the TMC-ETR by default
to prevent malfunctioning of systems where the ETR may not be
properly connected to the memory subsystem to allow for simultaneous
READ/WRITE transactions when used in SG mode. Instead we whitelist
the platforms where we know that it is safe to use the mode.
All revisions of Juno have a proper ETR connection and hence
white list them.
