The above include was added as a part of 3da52f308a ("ARM: i.MX:
esdctl: Add memory size detection for i.MX8MQ") in order to facilitate
memory size detection. I don't think it should be removed, since that
functionality isn't covered by upstream DTS. Moreso,
"imx8mq-ddrc.dtsi" needs to be updated to reference "soc@0" instead of
"peripherals@0".

Thanks,
Andrey Smirnov
