hw/nvme: add machine compatibility parameter to enable msix exclusive bar
Commit 1901b4967c3f ("hw/block/nvme: move msix table and pba to BAR 0")
moved the MSI-X table and PBA to BAR 0 to make room for enabling CMR and
PMR at the same time. As reported by Julien Grall in #2184, this breaks
migration through system hibernation.
Add a machine compatibility parameter and set it on machines pre 6.0 to
enable the old behavior automatically, restoring the hibernation
migration support.
