Floppy patches for 5.8

Browse source 
Cleanups:
   - symbolic register names for x86,sparc64,sparc32,powerpc,parisc,m68k
   - split of local/global variables for drive,fdc
   - UBSAN warning suppress in setup_rw_floppy()
 
 Changes were compile tested on arm, sparc64, powerpc, m68k. Many patches
 introduce no binary changes by using defines instead of magic numbers.
 The patches were also tested with syzkaller and simple write/read/format
 tests on real hardware.
