viafb: remove ioctls which break the framebuffer interface The ioctls VIAFB_SET_DEVICE, VIAFB_SET_DEVICE_INFO and VIAFB_SET_SECOND_MODE are removed because they prevent a clean framebuffer driver because they modify the hardware and/or the internal structures. There are no known applications using these ioctls so no breakage is expected. Additionaly the main functionality was duplicating the framebuffer interface so there really should not exist any user.
