ide: move ide_rate_filter() calls to the upper layer (take 2)
* Move ide_rate_filter() calls from host drivers to IDE core.
* Make ide_rate_filter() static.
* Make 'speed' argument of ->speedproc const.
v2:
* Fix it8213_tune_chipset() comment.
There should be no functionality changes caused by this patch.
