[PATCH v4 00/11] Actions S700 SoC support

[Amit Singh Tomar]

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.

This patch series can be tested using below tree:
