Again, this is a bit misleading as PCIe6a is using the
'qcom,x1e80100-qmp-gen4x4-pcie-phy' compatible in both 4-lane and 2-lane
mode even if the original dtsi got this wrong.

PCIe6b will be using 'qcom,x1e80100-qmp-gen4x2-pcie-phy' as that one is
a 2-lane PHY.

Perhaps you can rephrase this so that it doesn't sound like you are
using compatibles to configure PCIe6a?

Patch itself looks good.
