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

Add Qualcomm Crypto Engine device node for Monaco platform.
Bindings and Crypto DMA nodes for the same platform is already
present in the tree.

QCE and Crypto DMA nodes patch was applied as part of the
commit a86d84409947 ("arm64: dts: qcom: qcs8300: add QCrypto nodes"),
however was reverted due to compatible string being miss-matched
against schema.

Resubmitting the enablement of QCE device node for monaco platform
with compatible-string being aligned with qcom-qce schema.
