Simple sysctl-like firmware query interface. Similar in operation to the qemu one, and uses the same i/o ports but with different messaging. Requires the 'bootrom' option to be enabled.
This is used by UEFI (and potentially other BIOSs/firmware) to request information from bhyve. Currently, only the number of vCPUs is made available, with more to follow.
A very large thankyou to Ben Perrault who helped out testing an earlier version of this, and bhyve/Windows in general.
