Previous post install action results in loading wlan module during
sysinit. This is not possible since wlan device is only exposed after
wcnss-wlan service. This also delays ssh startup for approximately 3
minutes.

Loading wlan module should only be done on default runlevel, after
wcnss-wlan service has been started.

Also add a reference fb.modes file, although directfb applications still
doesn't work and cause the framebuffer driver to crash.
