Add board detection logic for the AM57xx EVM. More information about the EVM can be found here http://www.ti.com/tool/tmdxevm5728
The AM572x Evaluation Module provides an affordable platform to quickly start evaluation of Sitara. ARM Cortex-A15 AM57x Processors (AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI, machine vision, networking, medical imaging and many other industrial applications. It is a development platform based on the dual ARM Cortex-A15, dual C66x DSP processor that is integrated with tons of connectivity such as PCIe, SATA, HDMI, USB 3.0/2.0, Dual Gigabit Ethernet, and more.
The AM572x Evaluation Module also integrates video and 3D/2D graphics acceleration, as well as a quad-core Programmable Real-time Unit (PRU) and dual ARM Cortex-M4 cores.

The above change depends on a previous patch which introduces board_is_x15() and then builds on it, However, the patch is not submitted as a proper series in the right order.

Further, no such DTB exists in upstream kernel -> I suggest splitting out this specific change out of the series and repost once upstream kernel has support for the same.
