clk: imx: imx8mm: fix audio pll setting
commit 053a4ffe298836bb973d2cba59f82fff60c7db5b upstream. The AUDIO PLL max support 650M, so the original clk settings violate spec. This patch makes the output 786432000 -> 393216000, and 722534400 -> 361267200 to aligned with NXP vendor kernel without any impact on audio functionality and go within 650MHz PLL limit.
