No. I think we will have to stick with the scu_dev in global data, now
I see that it is needed just after relocation and before initr_dm(),
so we can't get it just after relocation via dm functions.

I'm working on ENET and I2C/USB/LVDS support for i.MX8QXP MEK based
on this patch series and will try to review remaining patches over
the weekend.

Thanks,
