hack for recognizing sensor on nv43

Hello, this is me again with my useful nv43.

As far as I can see nvidia binary driver can use integrated sensor on my card,
while nouveau can't. After some digging I found problem - nouveau can't find
some calibration coefficients in vbios. May be they missed completely, or bios
slightly misparsed. I'll attach again my vbios, and patch I made after looking
at nvclock sources [1]. Patch allow sensor to work, and reported temperature
roughly correspond to what I saw with binary driver (looking at raw output I
see nouveau still hotter than nvidia, but I can ignore this for now).

Not sure if such hack (?) should go into nouveau, or I (someone) better to find
if values really missed from vbios first.

Command for getting raw sensor value:
envytools/nva/nvapeek 0x15b4
