When updating the irq_chip and msi_domain_ops, the code checkes for
already present functions.
When more then one ITS controller are present in the system,
irq_chip and msi_domain_ops got already set and a warning is invoked.
This patch deletes the warning, as the funtions are just already set to

Up until now if the object version expected by a driver (in the API header
file) did not match the actual object version in the MC hardware the bus
driver refused to bind the object to the driver or printed out WARN_ON
dumps.
This patch removes those checks, and the responsibility of object version
checking should now be done in the object drivers themselves. If the actual
version discovered is not supported, the driver's probe function should fail.
Drivers should use version checks to support new features and provide
backwards compatibility if at all possible.
This patch also removes the checks that caused bus driver probing to fail
if the overall MC version discovered did not match the firmware version
from the API header...this was too strict. The overall MC version is
informational like a release number, and continues to be printed in the
boot log.
