EDAC/altera: Initialize peripheral FIFOs in probe()
The FIFO memory and ECC initialization doesn't need to be done as a separate operation early in the startup. Improve the Arria10 and Stratix10 peripheral FIFO init by initializing memory and enabling ECC as part of the device driver initialization.
