EDAC/altera: Handle OCRAM ECC enable after warm reset
The OCRAM ECC is always enabled either by the BootROM or by the Secure Device
Manager (SDM) during a power-on reset on SoCFPGA.
However, during a warm reset, the OCRAM content is retained to preserve data,
while the control and status registers are reset to their default values. As
a result, ECC must be explicitly re-enabled after a warm reset.
Fixes: 17e47dc6db4f ("EDAC/altera: Add Stratix10 OCRAM ECC support")
