[PATCH v3 hyperv-next 3/4] Drivers: hv: vmbus: Enforce 'VMBus version >= 5.2' on isolated guests

Restrict the protocol version(s) that will be negotiated with the host to be 5.2 or greater if the guest is running isolated. This reduces the footprint of the code that will be exercised by Confidential VMs and hence the exposure to bugs and vulnerabilities. Signed-off-by: Andrea Parri
