drm/i915/fbdev: fix link failure without FBDEV emulation

If CONFIG_DRM_FBDEV_EMULATION is disabled but CONFIG_FRAMEBUFFER_CONSOLE
is turned on, the i915 driver now fails to link:

ERROR: modpost: "intel_fbdev_fb_prefer_stolen" [drivers/gpu/drm/i915/i915.ko] undefined!

Fix the contition to include a check for the symbol that controls compilation
of intel_fbdev_fb.c.
