The implicit IDE, USB, and video controllers provided by the PIIX3
chipset in the pc-* machinetypes are not present on other
machinetypes, so we shouldn't be doing the special checking for them.
The diffs for this patch look hairy, but that's just because a large
section was reindented (to be placed inside a conditional) and git
couldn't figure out a sane diff. It really is just 1) determining if
this system uses PIIX3, 2) put the stuff that's PIIX3-specific inside
an if.
(Note that, according to the qemuxml2argv-pseries-usb-multi test, ppc
"pseries" machines also have a PIIX3 chip (since that test file adds a
"piix3-uhci" usb controller). I don't know if this is really the case
or not, but had to include that machine type in the checks in order
for make check to succeed with no changes to the test data.)
