arm64: dts: ti: k3-am62-main: Switch parent clocks of McASP

commit 63d2c44a52bab502128035222b99ae1104791ce3 from
git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git



McASP functional clock defaults to a non-audio friendly 100MHz
main_2_hsdivout8_clk clock source. Instead, switch to using a 96MHz
main_1_hsdivout6_clk.
