hardcoding it to on currently causes master to report unknown intr

b655f2bb77 drm/nve0/fb/gddr5: parse bios data into struct rather than using directly 
Still essentially a struct of magic values with magic names and unknown
purposes.  But, we will shortly need to be able to mix and match bits of
the previous and next configurations to do a transition reclock, as such,
we can no longer directly use the vbios data with any ease.

This is probably nicer anyway in the long run, for a few reasons.
