A user exception is triggered by inserting a bralid/brki jump to

separation, there are no code sequences that call into the user
exception
handler.
It seems there is no real usecase for having user exception support in
u-boot, so drop the code that installs the nop handler.
U-Boot still supports to run user code on the top of u-boot which
doesn't need
to handle these kind of exceptions. That's why it is good to jump to
this code
and let you know about it.
Thanks for the feedback, this patch should just be ignored then.
The rest of this series I think it's still a good addition to the
microblaze exception code.
