[PATCH 13/13] MMP DTS updates for 5.9

[Lubomir Rintel]

Hi,

chained to this message is a patch set I hope would end up queued into
soc/arm/dt for 5.9. It applies cleanly on top of v5.8-rc1.

I've checked I'm not adding new validation errors and booted the v5.8-rc1
kernels with appended DTBs on the XO-1.75 and Dell Ariel board.

Lubo
