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(v5) just re-orders the patches so that u-boot(with bubblegum96_defconfig) builds after every patch of the series(suggested by Andre).
First few patches(from 1/11 to 2/11) 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. Patches(from 6/11 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 2/11 to 4/11) with Linux(tag v5.5-rc6) and it is compiled-tested.
Patch(5/11) provides common clock driver that is used both by S900 and S700.
S700 support is tested[3] on Cubieboard7 board and S900 support is just compiled tested.
