Subject: [PATCH 2/8] arm64: dts: qcom: x1e78100-lenovo-thinkpad-t14s: Fix
 USB QMP PHY supplies

On the X1E80100 CRD, &vreg_l3e_1p2 only powers &usb_mp_qmpphy0/1
(i.e. USBSS_3 and USBSS_4). The QMP PHYs for USB_0, USB_1 and USB_2
are actually powered by &vreg_l2j_1p2.

Since x1e78100-lenovo-thinkpad-t14s mostly just mirrors the power supplies
from the x1e80100-crd device tree, assume that the fix also applies here.
