Subject: [PATCH] drivers: omap2: Kconfig: make FB_OMAP2_DSS_INIT depend on OF

Commit 7378f1149884 ("media: omap2: omapfb: allow building it with
COMPILE_TEST") broke compilation without CONFIG_OF selected.
  CC      drivers/video/fbdev/core/fbmem.o
drivers/video/fbdev/omap2/omapfb/dss/omapdss-boot-init.c: In function ‘omapdss_update_prop’:

  of_update_property(node, prop);

Add OF dependency in order to make all configurations work again.

of_update_property() has no inline stub, and that that could be added as
an alternative.
