fbdev: fbmem: mark get_fb_unmapped_area() static

There is a global function with this name on sparc, but no
global declaration:

drivers/video/fbdev/core/fbmem.c:1469:15: error: no previous prototype for 'get_fb_unmapped_area'

Make the generic definition static to avoid this warning. On
sparc, this is never seen.

Edit by Helge:
Update Kconfig text as suggested by Geert Uytterhoeven.
