* Fix icside, cris-ide, au1xxx-ide, amd74xx, via82cxxx and pmac host drivers
to use ide_rate_filter().
This results in the following modes (from user requests) being clipped down:
- invalid modes (values 0x46-0xFF) [ for all hosts ]
- unsupported by a host UDMA modes [ for hosts which support UDMA]
- all UDMA modes and MWDMA3-4 modes [ for hosts which doesn't support UDMA ]
- invalid modes (values 0x25-0x39) [ for hosts which doesn't support UDMA ]
* Host driver specific changes in behavior:
icside:
- no change
cris-ide
- clip unsupported UDMA3-6 modes down
- fix BUG() on trying to set unsupported UDMA3-6 modes
au1xxx-ide/pmac
- clip unsupported UDMA modes down
amd74xx/via82cxxx
- clip unsupported UDMA modes down
- fix random PIO timings being set for unsupported/invalid modes
- fix unsupported/invalid modes being set on the device
* While at it remove no longer needed checks from pmac.c driver.
