The registers in control of TH1520_RESET_ID_{NPU,WDT0,WDT1} don't belong
to the VO reset controller (documented as "thead,th1520-reset"), and
thus cannot be implemented by it. They're in fact AP subsystem resets,
which gets supported in Linux with this series.

Is it okay for you to separate a patch to delete these wrong IDs and add
them back for the AP reset controller latter? Anyway, I should have
provided more information about these three resets. Thanks for catching
this.
