I'm not sure about the above description, I'm not against removing
this option though.
IIUC, the usedac option enables us to stop via_no_dac() setting
forbid_dac to 1. That is, someone who uses VIA bridges can use DAC
with this option even if some of VIA bridges seem to be broken about
DAC. I can't see how we can do the same thing with "allowdac" and
"nodac" combination.
