board: add support for ARC AXS101 and AXS103 Software Development

Platforms

The AXS10x Platform consists of a DesignWare AXC001 CPU
Card (with ARC 770D core) in case of AXS101 or AXC003 CPU Card
(typically with ARC HS38 core) in case of AXS103 mounted on an
ARC Software Development Platform Mainboard with DesignWare peripherals:
 * SD/MMC contoller
 * Gigabit network contoller
 * Serial ports (8250-compatible)
 * USB 2.0
 * SPI
 * I2C

It also houses HDMI output for external monitor connection.
