hw/arm/xlnx-versal: reconnect the CRL to the other devices

Browse Source 
The CRL connects to various devices through link properties to be able
to reset them. The connections were dropped during the SoC refactoring.
Reintroduce them now.

Rely on the QOM tree to retrieve the devices to connect. The component
parts of the device names are chosen to match the properties on the CRL.
