System configuration registers are accessed through the regmap framework and the mfd/syscon driver. The implementation optionally supports waiting for the reset action to be acknowledged in a separate status register and supports both active high and active low reset lines. These properties are common across all the reset channels in a specific reset controller instance, hence all channels in a paritcular controller are expected to behave in the same way.

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.
