Subject: [PATCH 0/5] Add separate ICE UFS and eMMC device nodes for QCS615
 platform

This patch series introduces support for representing the Inline Crypto Engine (ICE)
as separate device nodes for both UFS and eMMC on the QCS615 platform.
Previously, ICE functionality was implicitly tied to the UFS/eMMC controllers.
With this update, ICE is modeled as an independent hardware block, allowing its
clock and frequency configuration to be managed directly by the ICE driver.
This separation improves modularity, aligns with hardware architecture.

The change allows the MMC/UFS controller to link to the ICE node for
crypto operations without embedding ICE-specific properties directly
in the MMC nodes.
