Hi, 

This is continuation of work[1], submitted(v2) almost a year back.

It 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).

First few patches(from 1/21 to 3/21) 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 4/21 to 6/21 and 10/21 to 12/21) enables S700 SoC support alongwith 
Cubieboard7 board.

While at it, took the opportunity to sync S900 DT sources and bindings(patches from 7/21 to 8/21) with 
Linux(tag v5.5-rc6) and it is compiled-tested.

Patch(9/21) uses same name for ethernet clock binding and if it's ok, would like to send it to LKML
as well.

Patches(from 13/21 to 14/21) adds support for RTL 8201F PHY module and introduce configuration option
"RTL8201F_PHY_S700_RMII_TIMINGS" to fulfill specific timing requirements for S700.

Patches(from 15/21 to 17/21) adds support for generic reset controller, originally used for NEXELL[3]
series but never gets merged and it can be used for S700.

Patches(from 18/21 to 21/21) are there to enable Ethenet support in S700, MAC is based on Designware IP
These patches re-uses the existing driver(drivers/net/designware.c) and programs SoC specific bits to
enable ethernet. SoC specific glue code is kept in dwmac_s700.c file, did it this way as found it more
cleaner(but having said that I am not really sure, if it's bit of a overkill to have it) or we can keep
this glue code somewhere in machine file?

S700 support is tested[4] on Cubieboard7 board and S900 support is just compiled tested.

Also, patches are rebased upon following commit:
2c871f9e084b2c03d1961884228a6901387ab8d6 Merge branch '2020-01-22-master-imports'

Thanks
