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

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 1be0000.phy: supply vdda-qref not found, using dummy regulator

Fixes: e961ec81 ("phy: qcom: qmp: Add phy register and clk setting for x1e80100 PCIe3")
