ARM: dts: ti: Add AM57xx GP EVM board support 



The AM57xx GP EVM boards are built on top the AM57xx BeagleBoard-X15.
The EVM extends the BeagleBoard by adding a touchscreen, some buttons,
and a handful of peripheral extension slots.

Being a plugin extension of an existing standalone board; we define
the am57xx-evm as a composite-DTB of the base am57xx-beagle-x15
and a new am57xx-evm overlay.
