Fixes linking fail when fbcon/fbdev is moduler and vgaswitcheroo is
enabled:

x86_64-linux-gnu-ld: drivers/gpu/vga/vga_switcheroo.o: in function `vga_switchto_stage2':
vga_switcheroo.c:(.text+0x997): undefined reference to `fbcon_remap_all'

Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
Reported-by: kbuild test robot <lkp@intel.com>
Fixes: 1cd51b5d200d ("vgaswitcheroo: call fbcon_remap_all directly")

wrt merging probably best if Maarten adds this to the topic branch we
have already and sends out an updated pull request.

Apologies for the mess.

Did you test this on a allmodconfig?

fbcon_remap_all is in a module, vga switcheroo is builtin, even with this patch you will still get the same compile failure.
