aec62xx: fix PIO/DMA setup issues
Teach the driver's tuneproc() method to do PIO auto-runing properly since it
treated 5 instead of 255 as auto-tune request, and also passed the mode limit
of PIO5 to ide_get_best_pio_mode() despite supporting up to PIO4 only.
While at it, also:
- remove the driver's wrong claim about supporting SWDMA modes;
- stop hooking ide_dma_timeout() method as the handler clearly doesn't fit for
the task...
