The altera_edac panic notifier performs some data collection with
regards errors detected; such code relies in the regmap layer to
perform reads/writes, so the code is abstracted and there is some
risk level to execute that, since the panic path runs in atomic
context, with interrupts/preemption and secondary CPUs disabled.

Users want the information collected in this panic notifier though,
so in order to balance the risk/benefit, let's skip the altera panic
notifier if kdump is loaded. While at it, remove a useless header
and encompass a macro inside the sole ifdef block it is used.
