The CS5530 at least shouldn't care what order changes are done. I don't
And neither CS5535. And Au1200 static bus controller shouldn't care about
the order too, so au1xxx-ide hardly needs that.
Here's the datasheet, BTW:

think the SC1200 does either but I don't have the docs to hand.
It seems pretty much alike CS553x except it's accessed via PCI config.
space, not MSRs... Here's the datasheet:

I have a feeling that only pdc202xx_new and jmicron drivers actually need
this flag (and the latter one actually doesn't care as its methods are empty
anyway). Well, AMD/VIA chips enable UltraDMA mode by snooping Set Features
command (as the drivers tell them to do so), so the order seems important
unless that is changed.
