Add MFD driver for SOCFPGA System Manager to handle
System Manager calls differently for ARM32 vs ARM64.
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.

v3 Changes:
Create and register regmap in probe().
Lookup functions find registered regmap.
Cleanup of header file.
Fix copyright dates.
Replace global pointer with traditional probe() methodology.
