arm64: dts: ti: k3-am62*: Move eMMC pinmux to top level board file
This moves pinmux child nodes for sdhci0 node from k3-am62x-sk-common to each top level board file. This is needed since we require internal pullups for AM62x SK and not for AM62 LP SK since it has external pullups on DATA 1-7. Internal pulls are required for AM62 SK as per JESD84 spec recommendation to prevent unconnected lines floating.
