ASoC: rt5651: Do not modify jd and PLL power bits from set_bias_level()
rt5651_set_bias_level(BIAS_OFF) used to unconditionally clear the entire register, including the jack-detect and PLL power bits. When jack-detection support was introduced a special case for jack-detect was added which hard-codes a register value to keep both on. This commit removes the jack-detect special case, instead simply leaving these bits as is on BIAS_OFF.
