[PATCH v2 1/5] arm64: dts: ti: k3-am6*: Set eMMC clock parents to default

Set eMMC clock parents to the defaults which is MAIN_PLL0_HSDIV5_CLKOUT
for eMMC. This change is necessary since DM is not implementing the
correct procedure to switch PLL clock source for eMMC and we have a
non-glich-free mux. To remove any potential issues, lets switch back to
the defaults.

Fixes: c37c58fdeb8a ("arm64: dts: ti: k3-am62: Add more peripheral nodes")
Fixes: d3ae4e8d8b6a ("arm64: dts: ti: k3-am62a-main: Add sdhci0 instance")
Fixes: b5080c7c1f7e ("arm64: dts: ti: k3-am62p: Add nodes for more IPs")
