Subject: [RFC PATCH v2 0/7] Add dedicated Qcom ICE driver

As both SDCC and UFS drivers use the ICE with duplicated implementation,
while none of the currently supported platforms make use concomitantly
of the same ICE IP block instance, the new SM8550 allows both UFS and
SDCC to do so. In order to support such scenario, there is a need for
a unified implementation and a devicetree node to be shared between
both types of storage devices. So lets drop the duplicate implementation
of the ICE from both SDCC and UFS and make it a dedicated (soc) driver.
Also, switch all UFS and SDCC devicetree nodes to use the new ICE
approach.

See each individual patch for changelogs.
