This gets iATU register area from reg property that has reg-names "atu".
In Synopsys DWC version 4.80 or later, since iATU register area is
separated from core register area, this area is necessary to get from
DT independently.

Use to_platform_device(dev) instead. Put that at the beginning as I'm

Okay, I'll rewrite it with to_platform_device(dev).
Should I refer somewhere to rebase to your change?
