ASoC: Intel: sof_rt5682: use RT5682S_PLL1 if needed

When 96KHz sample rate is used, and MCLK is 24.576MHz, we will need
pll_in = 24576000 and pll_out = 49152000 which is not supported by
RT5682S_PLL2. Use RT5682S_PLL1 in this case.
We don't test sample rate because RT5682S_PLL2 doesn't support 24.576MHz
input and in the MCLK = 24.576MHz, sample rate = 48KHz case, i.e.
pll_in == pll_out, PLL will not be used at all.
