omapfb -- panel initialization inflexibility

[Imre Deak]

Actually there is no requirement on calling panel->enable() before
omapfb_set_update_mode(), which enables the LCD DMA. It's even possible
to enable / disable the panel while having the LCD DMA active.

So lets simply switch the order of the two calls in omapfb_probe and the
suspend / resume functions. Please send a patch.
