regulator: ad5398: show changing current in uA
Integer division may truncate the result.
Current code shows changing current is 0mA when selector is 1 ... 8.
For example:
selector = 1
ad5398_calc_current returns 117, debug message shows 117/1000 = 0mA
selector = 2
ad5398_calc_current returns 234, debug message shows 234/1000 = 0mA
selector = 3
ad5398_calc_current returns 351, debug message shows 351/1000 = 0mA
............
selector = 8
ad5398_calc_current returns 937, debug message shows 937/1000 = 0mA
Show the changing current in uA makes it easier for debugging.
