[PATCHv4 1/3] arm: socfpga: dts: Add a syscon binding for sys-mgr

[dinguyen@altera.com (dinguyen at altera.com)]

From: Dinh Nguyen <dinguyen@altera.com>

The system manager block in SOCFPGA contains registers that control other
IPs in the SoC. Using the mfd/syscon driver is the best mechanism to
link the system manager to the other IPs.
