We'd disable this quirk in Fedora the moment jack detection works,
because we've got the userspace to handle it and using I2S is
preferable to using HDA - but in doing so we might break battery
detection on the other Dell that's playing _REV tricks. This seems
like a suboptimal choice to have to make.
