[RESEND 0/4] Add SOCFPGA System Manager

[thor . thayer]

From: Thor Thayer <thor.thayer@xxxxxxxxxxxxxxx>

Add MFD driver for ARM64 SOCFPGA System Manager to steer
System Manager calls appropriately.
The SOCFPGA System Manager includes registers from several
SOC peripherals.

On ARM32, syscon handles this aggregated register grouping.
Redirect System Manager calls 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.

  ARM: socfpga_defconfig: Enable CONFIG_MTD_ALTERA_SYSMGR
