rS330764: Add CR2 get/set support.

Summary

Allow bhyvectl to get/set the CR2 register.

Reported/Tested by: Fabien Freyer

Test Plan

Tested by dropping a single vCPU FreeBSD/amd64 guest into ddb, and verifying
that the value of CR2 from 'show sysregs' was the same as ready by
bhyvectl. The value was then set from bhyvectl, and 'show sysregs'
used to verify that the updated value was seen from the guest.
