phy: qcom-qmp-pcie: drop unused legacy DT workaround

Commit 5e17b95d ("phy: qcom-qmp: Utilize fully-specified DT
registers") added a workaround for legacy devicetrees which did not
specify register regions for the second lane of some dual-lane PHYs.

At the time, the only two dual-lane PHYs supported by mainline were
"qcom,sdm845-qmp-usb3-phy" and "qcom,sdm845-qmp-ufs-phy", neither
of which is a PCIe PHY.

Drop the workaround for malformed devicetrees, which should no longer be
needed since the QMP driver split.
