hwmon: (lm95245) Use HWMON_CHANNEL_INFO macro

Browse Source 
The HWMON_CHANNEL_INFO macro simplifies the code, reduces the likelihood
of errors, and makes the code easier to read.

The conversion was done automatically with coccinelle. The semantic patch
used to make this change is as follows.

-u32 i[] = {

-       .config = i,

    (String.concat ","
     (List.map (fun x -> Printf.sprintf "\n\t\t\t   %s" x)
       (Str.split (Str.regexp " , ") elements)))

This patch does not introduce functional changes. Many thanks to
Julia Lawall for providing the semantic patch.
