This patch adds .dtsi file(sync with Linux 4.20) and required binding
for S700 SoC that is a 64-bit Quad-core ARM Cortex-A53 cores.
Signed-off-by: Amit Singh Tomar <amittome...@gmail.com>

Changes since v1:
* Moved the u-boot specific changes to s700-u-boot.dtsi, now
s700.dtsi is in complete sync with Linux 4.20.
