This adds Cubieboard7[1] support based on Action Semi's S700 SoC[2], It's Quad-core ARMv8 SoC with Cortex-A53 cores. Peripheral like UART seems to be compatible with S900 SoC(basic support for it is alreay present in u-boot).
This series(v4) is much shorter than the previous series(v3) as patches related to Ethernet support is dropped along with reset driver patches.
First few patches(from 1/11 to 3/11) consolidates Actions Semiconductor SoCs support in u-boot(mostly insprired by SUXNI as suggested by Andre). Idea is to move every bit out from board/ucRobotics into arch/arm/mach-owl. It allows different SoCs to be driven by single "soc and Kconfig" file. It also includes common clock driver for S700 and S900. Patches(from 4/11 to 6/11 and 10/21 to 11/11) enables S700 SoC support alongwith Cubieboard7 board.
While at it, took the opportunity to sync S900 DT sources and bindings(patches from 7/11 to 8/11) with Linux(tag v5.5-rc6) and it is compiled-tested.
S700 support is tested[3] on Cubieboard7 board and S900 support is just compiled tested.
