phy: qcom: qmp-pcie: drop bogus x1e80100 qref supplies

The PCIe PHYs on x1e80100 do not a have a qref supply so stop requesting
one. This also avoids the follow warning at boot:

	qcom-qmp-pcie-phy 1bfc000.phy: supply vdda-qref not found, using dummy regulator

Fixes: 9dab00ee ("phy: qcom: qmp-pcie: Add Gen4 4-lanes mode for X1E80100")
Fixes: 606060ce ("phy: qcom-qmp-pcie: Add support for X1E80100 g3x2 and g4x2 PCIE")
