arm64: dts: ti: k3-am6*: Fix bus-width property in MMC nodes

Move bus-width property to *main.dtsi, above the OTAP/ITAP
delay values. While there is no error with where it is
currently at, it is easier to read the MMC node if the
bus-width property is located above the OTAP/ITAP delay
values consistently across MMC nodes.

Add missing bus-width for MMC2 in k3-am62-main.
