ASoC: tlv320aic32x4: Fix the divide by zero

The value of register(NDAC,MDAC,NADC,MADC,BCLKN) maybe zero lead to
divide by zero in clk_aic32x4_div_recalc_rate().And the rate should be
divide by 128 if the value was zero in this function according to the
datasheet.

Add the macro AIC32X4_DIV_MAX to present the 128 and return 0 if failing
to read the value of register.
