amiflop: fold headers into C file
amifd.h and amifdreg.h are only used from amiflop.c, and they're pretty small, so move the contents to amiflop.c and get rid of the .h files. This is preparation for adding a struct blk_mq_tag_set to struct amiga_floppy_struct. Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
