genirq/debugfs: Reinstate full OF path for domain name
On a DT based system, we use the of_node full name to name the
corresponding irq domain. We expect that name to be unique, so
so that domains with the same base name won't clash (this
happens on multi-node topoligies, for example).
Since a7e4cfb0a7ca ("of/fdt: only store the device node basename
in full_name"), of_node_full_name() lies and only returns the
basename. This breaks the above requirement, and we end-up with
only a subset of the domains in /sys/kernel/debug/irq/domains.
Let's reinstate the feature for the benefit of the irq subsystem
only.
Fixes: a7e4cfb0a7ca ("of/fdt: only store the device node basename in full_name")
