Hi, jermoe

Considering that the sample rate is up to 176.4K

PLL0 270.950400M max support 24bit *176.4k, 32ch for tdm mode

Perhaps PLL1 PLL1 calculation error , it should be set up 361.2672M for
32bit * 176.4k * 32ch.

In fact, most situations are limited by the speed of the IO pin.

Can we remove MPLL1 here and keep MPLL0?
