hyperv-fb: kick off efifb early

Remove firmware framebuffer before initializing hyperv-fb.  Needed
on gen2 virtual machines.   Letting register_framebuffer handle the
switchover results in efifb still being active while hyperv graphics
are initialized, which in turn can make the linux kernel hang.
