[PATCH v2 1/3] dt-bindings: crypto: qcom,ice: Add sa8255p support

[Linlin Zhang]

On sa8255p, resources such as PHY, clocks, regulators, and resets are
managed by remote firmware via the SCMI power protocol. As a result, the
ICE driver cannot directly access clocks and must instead use power-domains
to request resource configuration.

Add the qcom,sa8255p-inline-crypto-engine compatible string and make clocks
optional for platforms that use power-domains instead.
