Subject: [PATCH 1/2] config: omap2+: force fb and dss support as built-in

In certain board files, there are references to vram related functions
which are defined in drivers/video/omap2/vram.c. Because of this direct
dependency, CONFIG_FB_OMAP2 should be a built-in feature.

As per the current architecture, CONFIG_FB_OMAP2 is dependent on
CONFIG_OMAP2_DSS. Hence CONFIG_OMAP2_DSS support should also be selected
by default.
