Subject: [PATCH v3] dt-bindings: phy: qcom,sc8280xp-qmp-pcie-phy: Fix
 X1E80100 resets entries

The PCIe 6a PHY is actually Gen4 4-lanes capable. So the gen4x4 compatible
describes it. But according to the schema, currently the gen4x4 compatible
doesn't require both PHY and PHY-nocsr resets, while the HW does. So fix
that by adding the gen4x4 compatible alongside the gen4x2 one for the
resets description.
