sparc: Fix undefined reference to fb_is_primary_device

Browse source 
commit ed683b9bb91fc274383e222ba5873a9ee9033462 upstream.

Commit 55bffc8170 ("fbdev: Split frame buffer support in FB and FB_CORE
symbols") added a new FB_CORE Kconfig symbol, that can be enabled to only
have fbcon/VT and DRM fbdev emulation, but without support for any legacy
fbdev driver.

Unfortunately, it missed to change the CONFIG_FB in arch/sparc makefiles,
which leads to the following linking error in some sparc64 configurations:

   sparc64-linux-ld: drivers/video/fbdev/core/fbcon.o: in function `fbcon_fb_registered':
>> fbcon.c:(.text+0x4f60): undefined reference to `fb_is_primary_device'

Fixes: 55bffc8170 ("fbdev: Split frame buffer support in FB and FB_CORE symbols")
