hwmon: (adm1031) Fix coding style issues
Fix almost all coding style issues except for the multi-line macro errors, which do not really apply since the macros are not multi-line statements but declarations. Based on merged patch series from Zac Storer; fixed remaining checkpatch errors and warnings.
