Input: sun4i-ts - really fix A10 temperature reporting

Browse source

The commit titled: "Input: sun4i-ts -  A10 (sun4i) has a different
temperature curve" contains a math error, the offset it uses is in degrees,
but the actual code applies the offset before multiplying by stepsize :|

Given that this is rather backwards (every math course ever thought applies
the multiplication before the offset for linear functions), this commit
fixes things by changing the code applying the offset to do the logical
thing, adjusting the offset for the other models accordingly.

This has been tested on an A10, A13, A20 and A31 to make sure everything
really is correct now.
