boards: amlogic: Add FriendlyElec NanoPi K2 board support

Browse Source 
This adds platform code for the FriendlyElec NanoPi K2 board based on a
Meson GXBB (S905) SoC with the Meson GXBB configuration.

This initial submission only supports:
- UART
- MMC/SDCard
- Ethernet
- Reset Controller
- Clock controller

U-Boot for NanoPi-K2
====================
NanoPi-K2 is a single board computer manufactured by FriendlyElec
with the following specifications:
- Amlogic S905 ARM Cortex-A53 quad-core SoC @ 1.5GHz
- ARM Mali 450 GPU
- 2GB DDR3 SDRAM
- Gigabit Ethernet
- HDMI 2.0 4K/60Hz display
- 40-pin GPIO header
- 4 x USB 2.0 Host, 1 x USB OTG
- eMMC, microSD
- Infrared receiver
Schematics are available on the manufacturer website.
Currently the u-boot port supports the following devices:
- serial
- eMMC, microSD
- Ethernet
u-boot compilation
==================
> export ARCH=arm
> export CROSS_COMPILE=aarch64-none-elf-
> make nanopi-k2_defconfig
> make
Image creation
==============
Amlogic doesn't provide sources for the firmware and for tools needed
to create the bootloader image, so it is necessary to obtain them from
the git tree published by the board vendor:

Go back to mainline U-Boot source tree then :

> cp $FIPDIR/gxb/bl2.bin fip/
> cp $FIPDIR/gxb/acs.bin fip/
> cp $FIPDIR/gxb/bl21.bin fip/

> $FIPDIR/gxb/aml_encrypt_gxb --bootsig \

--output fip/u-boot.bin
and then write the image to SD with:
> DEV=/dev/your_sd_device
> dd if=fip/u-boot.bin of=$DEV conv=fsync,notrunc bs=512 seek=1
