of: of_probe: create board's machine device at the earliest
We currently create devices for matching reserved memory entries and
firmware before creating the machine device. In a deep probe system, the
machine driver would be probed directly at registration and as such
needs to be probed before other devices are created, so it can disable
other devices if needed. Move the machine device registration to the
top, so board drivers can disabled reserved memory entries and firmware
if they need to.
