Drivers: hv: Functions for setting up and tearing down the paravisor SynIC

Browse source

The confidential VMBus runs with the paravisor SynIC and requires
configuring it with the paravisor.

Add the functions for configuring the paravisor SynIC. Update
overall SynIC initialization logic to initialize the SynIC if it
is present. Finally, break out SynIC interrupt enable/disable
code into separate functions so that SynIC interrupts can be
enabled or disabled via the paravisor instead of the hypervisor
if the paravisor SynIC is present.
