rockchip: add support for Ariaboard Photonicat

This commit add basic support for Photonicat Board.

Flash into lede:
  Run first: dd if=openwrt-xxx.img of=/dev/mmcblk0
  Then brush the img file to sdcard and insert it,
  the system will boot from above.

Note:
  Since rockchip does not release any code to power up their
  device, disabled emmc for now until we can remove rkbin.
