arm: Add LibreTech CC support based on Meson GXL family

This adds platform code for the Libre Computer CC "Le Potato" board based on a Meson GXL (S905X) SoC with the Meson GXL configuration. This initial submission supports UART, MMC/SDCard and Ethernet with the Internal RMII PHY. The meson-gxl-s905x-libretech-cc.dts is synchronised from the linux 4.13 stable tree as of 4.13.8.

+U-Boot for LibreTech CC
+=======================
+
+LibreTech CC is a single board computer manufactured by Libre Technology
+with the following specifications:
+
+ - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 2GHz
+ - 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 libretech-cc_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:
+

+ > export FIPDIR=$PWD/fip
+
+Go back to mainline U-Boot source tree then :

	1	+U-Boot for LibreTech CC
	2	+=======================
	3	+
	4	+LibreTech CC is a single board computer manufactured by Libre Technology
	5	+with the following specifications:
	6	+
	7	+ - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 2GHz
	8	+ - ARM Mali 450 GPU
	9	+ - 2GB DDR3 SDRAM
	10	+ - Gigabit Ethernet
	11	+ - HDMI 2.0 4K/60Hz display
	12	+ - 40-pin GPIO header
	13	+ - 4 x USB 2.0 Host, 1 x USB OTG
	14	+ - eMMC, microSD
	15	+ - Infrared receiver
	16	+
	17	+Schematics are available on the manufacturer website.
	18	+
	19	+Currently the U-Boot port supports the following devices:
	20	+ - serial
	21	+ - eMMC, microSD
	22	+ - Ethernet
	23	+
	24	+U-Boot compilation
	25	+==================
	26	+
	27	+ > export ARCH=arm
	28	+ > export CROSS_COMPILE=aarch64-none-elf-
	29	+ > make libretech-cc_defconfig
	30	+ > make
	31	+
	32	+Image creation
	33	+==============
	34	+
	35	+Amlogic doesn't provide sources for the firmware and for tools needed
	36	+to create the bootloader image, so it is necessary to obtain them from
	37	+the git tree published by the board vendor:
