arm64: dts: imx8mp: Fix TC9595 input clock on DH i.MX8M Plus DHCOM SoM
The IMX8MP_CLK_CLKOUT2 supplies the TC9595 bridge with 13 MHz reference
clock. The IMX8MP_CLK_CLKOUT2 is supplied from IMX8MP_AUDIO_PLL2_OUT.
The IMX8MP_CLK_CLKOUT2 operates only as a power-of-two divider, and the
current 156 MHz is not power-of-two divisible to achieve 13 MHz.
To achieve 13 MHz output from IMX8MP_CLK_CLKOUT2, set IMX8MP_AUDIO_PLL2_OUT
to 208 MHz, because 208 MHz / 16 = 13 MHz.
