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.
