qseecom: Enable/disable clock for client if bus scaling is not enabled

To avoid the service failure on a target where bus scaling flag is not
enabled in target device tree file by mistake, make a change to enable/
disable crypto clocks when the client calls to scale up bus bandwidth
and send command even if bus scaling feature is not enabled.
