ASoC: nau8825: drop redundant idiom when converting integer to boolean

Thanks Mark and Anatol for the discussion. According to the result, the standard C will translate any non-zero value into true, or false otherwise. QUOTE: "6.3.1.2 Boolean type When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1 " Thus, the "!!" idiom is removed.
