[PATCH 5/5] arm64: dts: qcom: shikra: Add ICE, TRNG and QCE nodes

[Kuldeep Singh]

Add device tree nodes describing the crypto hardware blocks present
on the Qualcomm Shikra platform:

- BAM DMA controller used by the Qualcomm crypto engine
- QCE (crypto) engine with DMA support
- TRNG hardware random number generator
- Inline crypto engine (ICE)

Also connect the SDHC controller to ICE via "qcom,ice" property to
support inline encryption.
