[PATCHv2 2/4] arm: dts: Add a system manager compatible property

[dinguyen at altera.com]

From: Dinh Nguyen <dinguyen at altera.com>

The "altr,sysmgr-sdmmc-sdr" compatible property is used for the SOCFPGA
clk-sysmgr driver. This property represents the register inside the
system manager that controls the clock phase of the SD/MMC driver.

Also add "syscon" to the system manager node.
