I'll fix tmp112 parameters in another patch as as6200 patch 2 in v2
implements 2bytes read/write for the configure reg.

On another note, I checked all the supported chips in lm75 to see
which ones support an alert bit, only 3 chips support it; tmp112(bit 5 in the second byte),
tmp100, and tmp101 (bit 7 in the first byte).
