phy: qcom-qmp-ufs: drop legacy DT workaround

Commit 5e17b95d9893 ("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" and they had
been added to the binding less than six months before the binding was
fixed.

Presumably no one is using four-year old SDM845 dtbs with mainline
anymore so drop the workaround for malformed devicetrees. In the
unlikely event that anyone complains, we can consider reverting.
