[PATCH] vga_switcheroo: Depend upon fbcon being built-in, if enabled

[Daniel Vetter]

Fixes linking fail when fbcon/fbdev is modular 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'

v2: I first tried to fix this with an EXPORT_SYMBOL, but vga_switcheroo is
never a module, so this doesn't work.

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.
