MLK-20947 clk: imx: update the audio pll rate table on imx8mm
Audio PLL is a frac pll, the config for this PLL should follow
below limitation:
Fout = ((m + k / 65536) * FIN) / (p * 2^s),
Fvco = ((m + k / 65536) * FIN) / p
Fref = FIN / p
a). 6MHz <= Fref <= 25MHz;
b). 1 <= p <= 63;
c). 64 <= m <= 1023;
d). 0 <= s <= 6;
e). -32768 <= k <= 32767;
due to the frac part calculation deviation, frac pll 'recalc_rate'
is updated to look up the pll rate from table first.
