[PATCH] arm64: dts: imx8mq: remove SoC ID compatible

[Martin Kepplinger]

this reverts commit ce58459d8c7f4174e7b8a8ea903dd949631334a3 for imx8mq.

this is most likely not the real fix but works around the problem I have
(with v5.12-rc2) I want to report:

[    0.766925] SoC revision 0x21
[    0.770286] imx8_soc_info soc at 0: SoC revision via nvmem read failed: -517

This leads to the system not booting up.

This change makes use of the old way of reading soc_revision and thus
works around the problem.

What could be missing for the nvmem way to work here? Should it work
in any case? I assume so if you add the compatible to imx8mq.dtsi. But
if it would work, why keep the ocotp reads?

thanks a lot,
                             martin
