staging: iio: meter: ade7754: Match alignment with open parenthesis

Reorganize the parameters to improve the readability of the code in
two manners:
- parameters of distinctive variable types on different lines
- parameters of similar variable types on the same line

Also, take advantage of the horizontal space available and place
all the parameters on a single line.
