The PVR is a privileged read-only SPR. Test reading and writing in both supervisor and problem state. In supervisor state reading returns microwatt's assigned PVR number and writing is a noop. In problem state both reading and writing cause privileged instruction interrupts. Signed-off-by: Jordan Niethe <jniethe5@gmail.com>
