[PATCH v4] arm64: dts: qcom: x1e80100: Add crypto engine

[Harshal Dev]

On X Elite, there is a crypto engine IP block similar to ones found on
SM8x50 platforms.

Describe the crypto engine and its BAM.

The dt-binding schema update for the x1e80100 compatible is here
(already merged):
    
https://lore.kernel.org/all/20250213-dt-bindings-qcom-qce-x1e80100-v1-1-d17ef73a1c12@linaro.org/
---
Changes in v4:
- Updated iommu property to use 0x0 instead of 0x0000 in last cell.
- Updated dma-names property by listing one dma channel name per line.
- Use QCOM_ICC_TAG_ALWAYS symbol instead of 0 in the interconnects property.
- Link to v3: https://lore.kernel.org/r/20251127-crypto_dt_node_x1e80100-v3-1-29722003fe83@oss.qualcomm.com
---
Changes in v3:
- Fixed num-channels and qcom,num-ees properties by updating them to 20 and 4 respectively.
- Link to v2: https://lore.kernel.org/all/20250221-x1e80100-crypto-v2-1-413ecf68dcd7@linaro.org
Changes in v2:
- Added EE and channels numbers in BAM node, like Stephan suggested.
- Added v1.7.4 compatible as well.
- Link to v1: https://lore.kernel.org/r/20250213-x1e80100-crypto-v1-1-f93afdd4025a@linaro.org

Right as I hit enter for the rb message, I noticed the nodes you're
adding are not sorted - please sort them wrt the unit address (@foo)
and retain my tag then

Not sure if I understand you Konrad.. I believe the nodes are already sorted
since address (crypto) @1dfa000 > address (cryptobam) @1dc4000? Do let me know what
I'm missing.
