dts: socfpga: Add support for SD/MMC on the SOCFPGA platform

Introduce "altr,socfpga-dw-mshc" to enable Altera's SOCFPGA platform
specific implementation of the dw_mmc driver.

Also add the "syscon" binding to the "altr,sys-mgr" node. The clock
driver can use the syscon driver to toggle the register for the SD/MMC
clock phase shift settings.

Finally, fix an indentation error for the sysmgr node.

* Altera SOCFPGA specific extensions to the Synopsys Designware Mobile
Storage Host Controller
The Synopsys designware mobile storage host controller is used to interface
a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
differences between the core Synopsys dw mshc controller properties described
by synopsys-dw-mshc.txt and the properties used by the Altera SOCFPGA specific
extensions to the Synopsys Designware Mobile Storage Host Controller.
Required Properties:
