[ARM] 5028/1: pxafb: fix broken "backward compatibility way" in framebuffer
configuration Commit 84f43c308b73a6a12128288721a1007ba4f1a8da "pxafb: introduce register independent LCD connection type for pxafb" implements compatibility mode for old style pxafb_mach_info initialization data wrongly, causing the system to Oops repeatedly - first during probe, then when drawing. Fix it and make pxafb_decode_mach_info void.
