Tejun's recent eighty_ninty_three() fix has inspired me to do more thorough
review of the cable detection code...
* print user-friendly warning about limiting the maximum transfer speed
to UDMA33 (and the reason behind it) when 80-wire cable is not detected,
also while at it cleanup eighty_ninty_three() a bit
* use eighty_ninty_three() in ide_ata66_check(), this actually fixes 3 bugs:
- bit 14 (word 93 validity check) == 1 && bit 13 (80-wire cable test) == 1
were used as 80-wire cable present test for CONFIG_IDEDMA_IVB=n case
(please see FIXME comment in eighty_ninty_three() for more details)
- CONFIG_IDEDMA_IVB=y/n cases were interchanged
- check for SATA devices was missing
* remove private cable warnings from pdc_202xx{old,new} drivers now that core
code provides this functionality (plus, in pdc202xx_new case the test could
give false warnings for ATAPI devices because pdc202xx_new driver doesn't
even support ATAPI DMA)
