ARM: dts: add support for AM437x IDK The AM437x Industrial Development Kit (IDK) is an application development platform targeted at industrial communication and control applications. It comes with a 3-phase motor driver, PROFINET, PROFIBUS and a few other industrial communication interfaces. The board has 1GiB of DDR3 RAM, QSPI NOR flash, a 100% discrete power design (no PMIC) and an on-board 2MP camera (not supported with Linux as of this writing).

This has gone unnoticed because Linux doesn't use (as of now) that regulator at all, it's setup by the bootloader and left as is. While at that, also add missing reg property for our regulator.
