Revert "genirq: Restrict export of irq_to_desc()"

Browse Source 
This reverts commit 64a1b95bb9 and
commit 11cc92eb74.

Commit 64a1b95bb9 ("genirq: Restrict export of irq_to_desc()") removed
the export of irq_to_desc() and commit 11cc92eb74 ("genirq: Fix export
of irq_to_desc() for powerpc KVM") added it back with the powerpc KVM
limitation. But there's still some usage in GKI kernel modules, so
revert both two commits.
