Subject: [RFC PATCH v3 7/7] arm64: dts: qcom: sm8550: Add the Inline Crypto Engine node

Add support for UFS ICE by adding the qcom,ice property and the
ICE dedicated devicetree node. While at it, add the reg-name property
to the UFS HC node to be in line with older platforms.

Signed-off-by: Abel Vesa <abel.vesa@...aro.org>
---

Changes since v2:
 * dropped all changes for the older platforms
 * added the suppor for ICE with the new approach to the SM8550
