[PATCH v3] arm64: dts: qcom: monaco: add QCrypto node

[Abhinaba Rakshit]

Add Qualcomm Crypto Engine device node for Monaco platform.

QCE and Crypto DMA nodes patch was applied as part of
commit a86d84409947 ("arm64: dts: qcom: qcs8300: add QCrypto nodes"),
however was partially reverted by commit cdc117c40537 ("arm64: dts: qcom:
qcs8300: Partially revert "arm64: dts: qcom: qcs8300: add QCrypto nodes"")
due to compatible string being mismatched against schema.

QCE device node was reverted for Monaco platform as compatible-string
did not match with bindings schema.

This patch is intended in resubmitting the enablement of
QCE device node for Monaco platform with compatible-string
being aligned with qcom-qce.

Bindings and Crypto DMA nodes for the same platform is already
present in the tree.

...due to Qualcomm engineer not ever bothering to build test the code.

Was it build tested now? Typically this is implied by trusting people,
but not here. Trust is lost.

And to be clear - I found more QCrypto DTS patches which were never
build tested and never tested on the hardware. This was not a single
case, but a pattern.

Yes, the updated patch has now been build‑tested (including DT schema checks).
The previous issue happened due to an oversight on our end, and I agree that it should not have slipped through.
I’ll ensure future submissions are properly tested before sending them upstream.
