arm64: zynqmp: Use assigned-clock-rates for setting up clock in SOM
With limited low level configuration done via psu-init only IPs connected
on SOM are initialized and configured. All IPs connected to carrier card
are not initialized. There is a need to do proper reset, pin configuration
and also clock setting.
The patch targets the last part which is setting up proper clock for USBs
and SDs.
Also setup proper bus width for SD cards.
