cs5535: PIO fixes
* Fix cs5535_tuneproc() to pass PIO transfer mode value instead of PIO mode
number to cs5535_set_speed() (fixes random PIO timings being programmed
and a possible OOPS). Do a little cleanup while at it.
* Fix cs5535_set_speed() to check if the mate device is present (fixes PIO0
taskfile timings being used if there is no other device on the cable).
* Use cs5535_tuneproc() in cs5535_dma_check(). The old code had the same
issue as cs5535_tuneproc() and add additionally caused 0x00-0x04 transfer
mode values (== default PIO, default PIO w/ IORDY + two invalid values)
being set on the device instead of values 0x08-0x0c (XFER_PIO_[0,4]).
