[PATCH v2] arm64: dts: qcom: sm6350: Add Crypto Engine

[Luca Weiss]

Add crypto engine (CE) and CE BAM related nodes and definitions for this
SoC.

For reference:

  [    2.297419] qcrypto 1dfa000.crypto: Crypto device found, version 5.5.1

Add the compatible and nodes for the QCE found on SM6350 SoC.

Not completely sure how to fully test it but "kcapi-speed --all" shows
no issues. Let me know if I can/should test this more.

Changes in v2:
- Drop applied patch
- Sort iommu entries & drop extra leading zeroes from mask
- Link to v1: https://lore.kernel.org/r/20240105-sm6350-qce-v1-0-416e5c7319ac@fairphone.com
