Zoltan HERPAI 99545b4bb1 d1: add new target 
This target adds support for the Allwinner D1 RISC-V based SoCs.

 - RISC-V single-core T-Head C906 (RV64GCV)
 - Tensilica HiFi4 DSP
 - DDR2/DDR3 support
 - 10/100/1000M ethernet
 - usual peripherals like USB2, SPI, I2C, PWM, etc.

Four boards are supported:
 - Dongshan Nezha STU
    - 512Mb RAM
    - ethernet

 - LicheePi RV Dock
    - 512Mb RAM
    - wireless-only (RTL8723DS)

 - MangoPi MQ-Pro
    - 512Mb RAM
    - there are pads available for an SPI flash
    - wireless-only (RTL8723DS)

 - Nezha D1
    - 512Mb/1Gb/2Gb RAM
    - 256Mb NAND flash
    - ethernet, wireless

Installation:
Standard SD-card installation via dd-ing the generated image to
an SD-card of at least 256Mb.
