[PATCH v3 07/33] swim: Refactor SWIM setup

[Finn Thain]

The write to the setup register is really chip initialization, so do it in
swim_floppy_init() rather than floppy_open(). Drop the udelay(), which was
apparently copied and pasted from swim3.c where it presumably relates to
interrupts, of which this chip has none. (See also mkLinux SWIM 3 driver.)
