[PATCH PATCH 6.12.y] dt-bindings: crypto: qcom,ice: Fix missing power-domain and iface clk

[ Upstream commit e27264daac7d9ce892a2a5b4a864d6d9a3c9276a ]

The DT bindings for inline-crypto engine do not specify the UFS_PHY_GDSC
power-domain and iface clock. Without enabling the iface clock and the
associated power-domain the ICE hardware cannot function correctly and
leads to unclocked hardware accesses being observed during probe.

Extend and fix the DT bindings for inline-crypto engine by allowing
description of the iface clock and UFS_PHY_GDSC power-domain.

This patch has been adapted from the mentioned upstream commit to drop
references to Eliza and Milos Qualcomm platforms which do not exist
on the stable tree. Thus, patch now fixes the original commit which
introduced the DT binding for Qualcomm inline-crypto engine.
