Bug 2358217 (CVE-2025-22012)

In the Linux kernel, the following vulnerability has been resolved:

Revert "arm64: dts: qcom: sdm845: Affirm IDR0.CCTW on apps_smmu"

There are reports that the pagetable walker cache coherency is not a
given across the spectrum of SDM845/850 devices, leading to lock-ups
and resets. It works fine on some devices (like the Dragonboard 845c,
but not so much on the Lenovo Yoga C630).

This unfortunately looks like a fluke in firmware development, where
likely somewhere in the vast hypervisor stack, a change to accommodate
for this was only introduced after the initial software release (which
often serves as a baseline for products).

Revert the change to avoid additional guesswork around crashes.

This reverts commit 6b31a9744b8726c69bb0af290f8475a368a4b805.
