[PATCH] arm64: dts: qcom: remove the disabled replicator

[Jie Gan]

Remove the disabled device that blocks probing of the connected
replicator, as the replicator driver validates all connected
devices during probe.

kernel log:
[   18.540971] platform 6046000.replicator: deferred probe pending: (reason unknown)

No, that's not a reason to remove a device. The device is there, right?
So fix Linux drivers if they cannot handle it properly.

Best regards,
Krzysztof

CoreSight devices build a path from source to sink and defer probing if 
any device in the path is unavailable so the deferred‑probe behavior is 
expected.

We could add logic to fix it in driver but it's much easier to address 
it in DT because we are knowing the device is disabled/Failed in DT.

It's my fault I didnt remove this disabled replicator device in previous 
fix.

Thanks,
Jie

Nope. You got comment already. DTS represents the hardware, not your
current Linux driver status.

Thanks for the patience to explain it, I have submitted a driver patch 
to address it.
