nwztools/plattools: fix black screen issue in dualboot, rework dualboot

Sony added extensions to the frambuffer interface. It is important to take them
into account since the OF uses them and might leave the framebuffer in an
unusual state which would make the dualboot not display anything. Also rework
the dualboot code so that it can boot rockbox (not doing anything at the moment),
display all tools or boot the OF.
