From: Arnd Bergmann <arnd@arndb.de>
The two hyperv framebuffer drivers (hyperv_fb or hyperv_drm_drv) access the
global screen_info in order to take over from the sysfb framebuffer, which
in turn could be handled by simplefb, simpledrm or efifb. Similarly, the
vmbus_drv code marks the original EFI framebuffer as reserved, but this
is not required if there is no sysfb.
As a preparation for making screen_info itself more local to the sysfb
helper code, add a compile-time conditional in all three files that relate
to hyperv fb and just skip this code if there is no sysfb that needs to
be unregistered.
