irqchip/gic-v3: Fix ppi-partitions lookup

Browse source

commit 00ee9a1ca5 upstream.

Fix child-node lookup during initialisation, which ended up searching
the whole device tree depth-first starting at the parent rather than
just matching on its children.

To make things worse, the parent gic node was prematurely freed, while
the ppi-partitions node was leaked.
