[PATCH 2/3] arm64: dts: imx91: Assign media_{axi,apb}_root clock parents/rates

According to i.MX91 SoC reference manual, maximal clock frequencies
in nominal drive mode for media_axi_root and media_apb_root clocks
are 333.33MHz and 125MHz respectively.  Assign the clock parents to
be IMX93_CLK_SYS_PLL_PFD0 @ 1GHz and IMX93_CLK_SYS_PLL_PFD0_DIV2 @
500MHz respectively and assign the maximal clock rates by overriding
the original settings in imx91_93_common.dtsi.  This would effectively
achieve media_axi_root clock running at 333.333334MHz and media_apb_root
clock running at 125MHz, which aligns to NXP downstream kernel settings.
