Use the EDAC-specific wrappers. Drop CONFIG_EDAC_DEBUG ifdeffery.

Suspend-to-RAM and EDAC support are mutually exclusive on SOCFPGA. If
EDAC is enabled, it will prevent the platform from going into suspend.
The reason is that the IRQ vectors for OCRAM reside on DDR and in
Suspend-to-RAM mode we're executing out of OCRAM. If an ECC error
occurs, we can't handle it so it was decided to make them mutually
exclusive.

The Arria10 SDRAM and ECC system differs significantly from the
Cyclone5 and Arria5 SoCs. This patch adds support for the Arria10
SoC.
1) IRQ handler needs to support SHARED IRQ
2) Support sberr and dberr address reporting.

The Arria10 SoC uses a completely different SDRAM controller from the
earlier CycloneV and ArriaV SoCs. This patch abstracts the SDRAM bits
for the CycloneV/ArriaV SoCs in preparation for the Arria10 support.

The Arria10 SOC uses a completely different SDRAM controller from the
earlier CycloneV and ArriaV SoCs. The memory size is calculated in the
bootloader and passed via the device tree. Using this device tree size
is more generic than using the register fields to calculate the memory
size for different SDRAM controllers.

This patch adds support for the CycloneV and ArriaV SDRAM controllers.
Correction and reporting of SBEs, Panic on DBEs.
There was a discussion thread on whether this driver should be an mfd driver
or just make use of syscon, which is already a mfd. Ultimately, the
decision to use a simple syscon interface was reached.[1]
