rockchip: board: lion-rk3368: add support for the RK3368-uQ7

The RK3368-uQ7 (codenamed 'Lion') is a micro-Qseven (40mm x 70mm,
MXM-230 edge connector compatible with the Qseven specification)
form-factor system-on-module based on the octo-core Rockchip RK3368.
It is designed, supported and manufactured by Theobroma Systems.

It provides the following features:
 - 8x Cortex-A53 (in 2 clusters of 4 cores each)
 - (on-module) up to 4GB of DDR3 memory
 - (on-module) SPI-NOR flash
 - (on-module) eMMC
 - Gigabit Ethernet (with an on-module KSZ9031 PHY)
 - USB
 - HDMI
 - MIPI-DSI/single-channel LVDS (muxed on the 'LVDS-A' pin-group)
 - various 'slow' interfaces (e.g. UART, SPI, I2C, I2S, ...)

+Here is the step-by-step to boot to U-Boot on RK3368-uQ7
+
+Get the Source and build ATF
+============================
+
+  > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
+  > cd arm-trusted-firmware
+  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3368 bl31
+  > cp build/rk3368/release/bl31.bin ../u-boot/bl31-rk3368.bin
+
+Configure U-Boot
+================
+
+  > cd ../u-boot
+  > make lion-rk3368_defconfig
+
+Build the TPL/SPL stage
+=======================
+
+  > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm
+  > tools/mkimage -n rk3368 -T rksd -d tpl/u-boot-tpl.bin spl-3368.img
+  > cat spl/u-boot-spl-dtb.bin >> spl-3368.img
+
+Build the full U-Boot and a FIT image including the ATF
+=======================================================
+
+  > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm u-boot.itb
+
+Write to a SD-card
+==================
+
+  > dd if=spl-3368.img of=/dev/sdb seek=64
+  > dd if=u-boot.itb of=/dev/sdb seek=512
+
+
+If everything went according to plan, you should see the following
+output on UART0:
