omapfb provides several sysfs interfaces for framebuffer configuration and debugging, but these are not required for the core driver. Remove the hard dependency on CONFIG_FB_DEVICE and make sysfs support optional by using dev_of_fbinfo() to obtain the backing device at runtime. When FB_DEVICE is disabled, sysfs operations are skipped while the code still builds and is type-checked.

Select the number of framebuffers created. OMAP2/3 has 3 overlays

so normally this would be 3.
