4.9-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 6faecba0b3da7b617bf72bef422bf0d3bb6dfe7d ]
Seems like coefficient values for m, b and R under power have been put in the wrong order. Rearranging them properly to get correct values of coefficients for power.
For specs, please refer to table 7 (page 35) on http://www.analog.com/media/en/technical-documentation/data-sheets/ADM1075.p...
