Subject: [PATCH 1/8] arm64: dts: qcom: x1e001de-devkit: 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 x1e001de-devkit mostly just mirrors the power supplies from the
x1e80100-crd device tree, assume that the fix also applies here.
