Subject: [PATCH v2] arm64: dts: qcom: lemans: add QCrypto node

Add Qualcomm Crypto Engine device node for LeMans platform.

QCE and Crypto DMA nodes patch was applied as part of the
commit 7ff3da43ef44 ("arm64: dts: qcom: sa8775p: add QCrypto nodes"),
however was partially reverted by commit 92979f12a201 ("arm64: dts: qcom:
sa8775p: Partially revert "arm64: dts: qcom: sa8775p: add QCrypto nodes"")
due to compatible-string being miss-matched against schema.

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

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

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

Changes in v2:
- Update the commit message and cover-letter description.
- Set the interconnect tag to QCOM_ICC_TAG_ALWAYS instead of passing 0(no TAG).
- Link to v1: https://lore.kernel.org/r/20251223-enable-qualcomm-crypto-engine-for-lemans-v1-1-f2c8f8e4f3cd@oss.qualcomm.com
