linux-postmarketos-qcom-laptop: backport DMA range fix for >32GB snapdragon x devices

Ariadne Conillrequested to merge
kaniini/pmaports:fix/qcom-x1e-64gb into master

x1e series devices have a 40-bit physical address bus, which is relevant for devices with more than 32GB of memory.

Previously DMA would be set up inside the upper address range, which would result in kernel crashes due to memory corruption.
