I don't believe this clock should be here:
(1) the rk3568 dts node later in the series doesn't use it at all
(2) generally vio-clocks are part of the interconnect where the ip block
connects to, so right now we just enable it as critical on all socs and
if someone actually models the interconnect (where also the qos
[quality of service configs] nodes would play into), it would need to
be included there.
