[RFC 06/13] ARM: dts: am57xx-evm: add AM57xx-evm DT overlay

[Tero Kristo <t-kristo@ti.com>]

The AM57xx-evm is an overlay on top of beagle-x15 board. This contains
a display extension macro, and a few extra peripherals. Two versions
of the evm are supported, the base evm and the latest rev A3 evm. A
common overlay file is used for both boards.
