Subject: [PATCH 1/5] dt-bindings: mmc: add qcom,ice phandle to mmc

Add the 'qcom,ice' phandle to the MMC device tree binding to support
reference to an Inline Crypto Engine (ICE) device node.

ICE hardware is now represented as a separate device node, and its
clock and frequency configuration are managed independently by
the ICE driver.
