ARC: HSDK-4xD: add initial board support
Add initial HSDK-4xD board support. The ARC HS4x/HS4xD Development Kit includes a multicore ARC HS4xD-based chip that integrates a wide range of interfaces including Ethernet, HDMI, WiFi, Bluetooth, USB, SDIO, I2C, SPI, UART, I2S, ADC, PWM and GPIO, as well as a Think Silicon GPU.
