[Xenomai] [PATCH] Revert "ipipe: ipipe_request_irq(), ipipe_free_irq() are root-only services"

[Jan Kiszka <jan.kiszka@siemens.com>]

This reverts commit 073ff1e8045d0311b8cf390687c0ba3619681672.

Both service are NOT just root-only services. E.g., rtdm_irq_request
requires by specification support also over non-Linux contexts.

We run all critical code under an I-pipe spin lock, so this restriction
seems artificial. Nevertheless, I briefly checked if some arch has
specific needs but didn't find any trace in core-3.5.

Wolfgang, this already resolves the issue I mentioned regarding startup
of RTnet NICs.
