video: omapfb: Fix fall-through warning for Clang

Fix the following fallthrough warnings:

drivers/video/fbdev/omap/omapfb_main.c:1558:2: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough]
           case 0:
           ^
   drivers/video/fbdev/omap/omapfb_main.c:1558:2: note: insert 'break;' to avoid fall-through
           case 0:
           ^
           break;
   1 warning generated.

This helps with the ongoing efforts to globally enable
-Wimplicit-fallthrough for Clang.
