irqdomain/debugfs: Use PAs to generate fwnode names
Booting a large arm64 server (HiSi D05) leads to the following
shouting at boot time:
[ 20.722132] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!
[ 20.730851] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!
[ 20.739560] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!
[ 20.748267] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!
[ 20.756975] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!
[ 20.765683] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!
[ 20.774391] debugfs: File 'irqchip@(____ptrval____)-3' in directory 'domains' already present!
and many more... Evidently, we expect something a bit more informative
than ____ptrval____, and certainly we want all of our domains, not just
the first one.
For that, turn the %p used to generate the fwnode name into something
that won't be repainted (%pa). Given that we've now fixed all users to
pass a pointer to a PA, it will actually do the right thing.
