Subject: [PATCH v3] dt-bindings: soc: altera: convert socfpga-system.txt to yaml

From: Niravkumar L Rabara <niravkumar.l.rabara@...el.com>

Convert socfpga-system.txt to altr,socfpga-sys-mgr.yaml and move to
soc directory.

Add platform names in description for clarity. ARM(32-bit) platforms
Cyclone5, Arria5 and Arria10 is using "altr,sys-mgr" compatible,
while ARM64 is using "altr,sys-mgr-s10" compatible.
Removed "cpu1-start-addr" for ARM64 as it is not required.

Signed-off-by: Niravkumar L Rabara <niravkumar.l.rabara@...el.com>
