EDAC, altera: Add Stratix10 peripheral support
...
Add a new peripheral ECC error injection algorithm for Stratix10 and
some Arria10 peripherals. Inject a single bit error and upon readback,
it will be corrected and the SBE IRQ handler will be called.
Add regmap selection for Stratix10 or Arria10 peripheral device memory
initialization.
Add checks for both Arria10 and Stratix10 to the peripheral ECC setup.

EDAC, altera: Merge Stratix10 into the Arria10 SDRAM probe routine
...
Change Stratix10 regmap to use offsets from a base to match
the Arria10 regmap and allow re-use of the Arria10 functions.
Only the regmap initialization differs (Arria10 mmio_regmap
vs Stratix10 custom regmap).
Modify the SDRAM probe function to handle Stratix10. Remove the
Stratix10 offset defines if Arria10 can be used. Remove the unused
Stratix10 probe function.

EDAC, altera: Combine Stratix10 and Arria10 probe functions
...
On Stratix10, the ECC offsets are similar to the existing
Arria10 functions and this can be leveraged to simplify
the EDAC driver as follows:
1. Fold Stratix10 specifics into Arria10 structures and
functions.
2. Implement the Stratix10 System Manager register accesses
using a custom regmap to allow use with the Arria10 System
Manager regmaps.
3. Stratix10 double bit errors are implemented as SError
instead of interrupts so use a panic notifier.

EDAC, altera: Handle SDRAM Uncorrectable Errors on Stratix10
...
On Stratix10, uncorrectable errors are routed to the SError exception
instead of the IRQ exceptions. In Stratix10, uncorrectable SErrors
must be treated as fatal and will cause a panic. Older Altera/Intel
parts printed out a message for UE so do that here using the notifier
framework.
Record the UE in sticky registers that retain the state through a reset.
Check these registers on probe and printout the error on startup.

In preparation for additional memory module ECCs, the IRQ function will
check a panic flag before doing a kernel panic on double bit errors.
OCRAM uncorrectable errors cause a panic because sleep/resume functions

ECCs on peripheral FIFO buffers will not cause a kernel panic on DBERRs
because the packet can be retried and therefore recovered.
