microblaze: convert all simple headers to use asm-generic All the simple microblaze header files were adapted to use their asm-generic implementations. These files are more simple and were quite straightforward to change. fb.h, vga.h and parport.h previously did not exist, using the generic version makes it possible to build more drivers successfully in allyesonfig.
