Paul Fertser d4a6139e65 hwmon: (tmp421) fix rounding for negative values ...

[ Upstream commit 724e8af858 ]

Old code produces -24999 for 0b1110011100000000 input in standard format due to
always rounding up rather than "away from zero".

Use the common macro for division, unify and simplify the conversion code along
the way.
