This adds BL31 support to Intel Stratix10 SoCFPGA platform. BL31 in TF-A
supports:
- PSCI calls to enable 4 CPU cores
- PSCI mailbox calls for FPGA reconfiguration

A DDR calibration value is missing write mask, causing ECC DDR calibration
to fail. This patch addresses the issue. ECC should also be scrubbed before
MMU initializes, thus the scrubbing is moved to ddr intialization phase.
