irqdomain: Move revmap_trees_mutex to struct irq_domain
The revmap_trees_mutex protects domain->revmap_tree. There is no
need to make it global because it is allowed to modify revmap_tree
of two different domains concurrently. Having said that, this would
not be a actual bottleneck because the interrupt map/unmap does not
occur quite often. Rather, the motivation is to tidy up the code
from a data structure point of view.
