PATCH v3 1/1 arm: boards: Add support for MYIR MYD-AM335X Development Board

The MYD-AM335X Development Board designed by MYIR is a high-performance ARM Evaluation Module (EVM) using the MYC-AM335X CPU module as the core controller board. It is based on up to 1GHz Texas Instruments (TI) Sitara AM335x family of ARM Cortex-A8 Microprocessors (MPUs) that deliver high DMIPs at a low cost while also delivering optional 3D graphics acceleration and key peripherals.
