EDAC/altera: Use INTTEST register for Ethernet and USB SBE injection

The current single-bit error injection mechanism flips bits directly in ECC RAM
by performing write and read operations. When the ECC RAM is actively used by
the Ethernet or USB controller, this approach sometimes trigger a false
double-bit error.

Switch both Ethernet and USB EDAC devices to use the INTTEST register
(altr_edac_a10_device_inject_fops) for single-bit error injection, similar to
the existing double-bit error injection method.
