[Nouveau] [PATCH] drm/nouveau/clk: fix crystal frequency retrieval on nv25

Hi,

this fixes a regression I have seen since the kernel module rewrite in summer. After loading nouveau, screen would go 
all black and monitor would show "Out of range". According to envytools' hwdocs/pstraps.txt nv25 should use both pstraps
bits(6 & 22) so I hope this fix is valid for all nv25 cards, not just mine.

Best regards
Viktor
