sparc: Clear out unused asm/machines.h values.

Browse Source 
Remove sun4 and sun4c machine ID values from asm/machines.h

Also kill NUM_SUN_MACHINES, use ARRAY_SIZE instead.

Kill asm/machines.h include and sun4c checks from asm/floppy_32.h

Remove asm/machines.h include from setup_32.c and time_32.c, unused.
