6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stephan Gerhold <stephan.gerhold@xxxxxxxxxx>
commit c0562f51b177d49829a378b5aeda73f78c60d0fc upstream.
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 x1e80100-microsoft-romulus mostly just mirrors the power supplies
from the x1e80100-crd device tree, assume that the fix also applies here.
