> Currently when busy polling is enabled we aren't setting/enabling
> WB_ON_ITR in the driver. This doesn't break the driver, but it does cause
> issues. If we don't enable WB_ON_ITR mode we will still get write-backs
> from hardware during polling when a cache line has been filled, but if a cache
> line is not filled we will not get the write-back because WB_ON_ITR is not set.
> Fix this by enabling WB_ON_ITR in the driver when interrupts are disabled.
