Like to panic by default when the machine is booted normally but to be
able to turn off the panicking with a module parameter?
If so, then you could probably implement a trivial setter called
edac_mc_set_panic_on_ue() in a separate patch.
Then, you call it at the end of altr_sdram_probe().
If you want to turn it off again, you do
echo "0" > /sys/module/edac_core/parameters/edac_mc_panic_on_ue
Something like that...
