[questing] Revert "arm64: dts: qcom: sc8280xp: Enable GPI DMA"

[Impact]
The offending commit breaks the live ISO on all sc8280xp devices.
We see a hang early on the in initrd followed by:
gpi 800000.dma-controller: Error with cmd: CH START completion timeout
gpi 800000.dma-controller: Error with cmd: DE ALLOC ret:-5

We have confirmed this affects at least the Thinkpad X13s and Microsoft
Windows Dev Kit 2023.

[Fix]
For now the preferred fix would be to revert commit
013d01811a1ea4ce0f676e4110f94c80271586b9
which added the problematic nodes to the device trees of the affected devices.
I have produced a test iso on Launchpad with this commit reverted and
verified that solves
the problem for now available at

In the long term we might have to explore other solutions such as
changing the list of modules included
in the initrd, but the revert buys us time to consult with upstream.
