The reset array size is currently used for bounds checking in the reset driver. The same bounds check should really be done in the clock driver. Currently, the array size is provided to the reset driver separately from the CCU descriptor, which is a bit strange. Let's do this the usual way, with the array sizes next to the arrays themselves.
