firmware: psci: Fix refcount leak in psci_dt_init

Browse Source 
[ Upstream commit 7ff37d29fd5c27617b9767e1b8946d115cf93a1e ]

Fix a reference counter leak in psci_dt_init() where of_node_put(np) was
missing after of_find_matching_node_and_match() when np is unavailable.

Fixes: d09a0011ec ("drivers: psci: Allow PSCI node to be disabled")
