The SOCFPGA System Manager includes registers from several SOC peripherals. On ARM32, syscon handles this aggregated register grouping. Implement System Manager calls as regmap_mmio similar to syscon for ARM32 SOCFPGA systems. The ARM64 System Manager can only be accessed from priority level EL3 so this new MFD driver handles the calls to EL3.
