Merge patch series "board: ti: k3-am65: covert last board to OF_UPSTREAM"

Bryan Brattlof <bb@ti.com> says:

Hello Everyone!

This small series converts TI's AM65x reference board to use
CONFIG_OF_UPSTREAM and removes the unused device tree files from
arch/arm/dts.

Because it's the last board using a AM65x without enabling OF_UPSTREAM
it allows us to also remove all the SoC FDT files as well and keep a
single version of the SoC's DT files in the dts/upstream directory going
forward.
