boards.h: Ignore migration for SMBus devices on older machines 



Migration capability is being added for pm_smbus and SMBus devices.
This change will allow backwards compatibility to be kept when
migrating back to an old qemu version.  Add a bool to the machine
class tho keep smbus migration from happening.  Future changes
will use this.
