[PATCH] arm: boards: Add support for MYIR MYD-AM335X Development Board

[Alexander Shiyan <eagle.alexander923@gmail.com>]

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.
