Indeed, names and DISP0_RESET_N and MDP_VSYNC, will rename.

Without PMIC GLINK/UCSI, there's no mode switch source, so otg is not possible,
and bootloader leaves the PMIC power state in peripheral mode.

On the other side with the next patch, we add pmic-glink and we add
"usb-role-switch" making it switchable.
