board/firefly_rk3288: add new board

This commit adds basic configuration files for the Firefly RK3288 board.
Both minimal and demo defconfigs are added. The latter enables Qt5 with
the required Mali T76X GPU user space components.

+Firefly RK3288
+
+How to build it
+===============
+
+  $ make firefly_rk3288_defconfig
+
+Then you can edit the build options using
+
+  $ make menuconfig
+
+Compile all and build rootfs image:
+
+  $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+  output/images/
+  ├── rk3288-firefly.dtb
+  ├── rootfs.ext2
+  ├── rootfs.ext4 -> rootfs.ext2
+  ├── sdcard.img
+  ├── u-boot-dtb.img
+  ├── u-boot-spl-dtb.bin
+  ├── u-boot-spl-dtb.img
+  └── uImage
+
+Prepare your SDCard
+===================
+
+Buildroot generates a ready-to-use SD card image that you can flash directly to
+the card. The image will be in output/images/sdcard.img.
+You can write this image directly to an SD card device (i.e. /dev/xxx):
+
+  $ dd if=output/images/sdcard.img of=/dev/xxx
+
+Finally, you can insert the SD card to the Firefly RK3288 board and boot it.
