firmware: arm_scpi: fix device_node leak in scpi_dev_domain_id

Browse source

of_parse_phandle_with_args() takes a reference on clkspec.np that must be
released with of_node_put(). scpi_dev_domain_id() returned clkspec.args[0]
without dropping that reference, so every domain lookup leaked a device
node. Paths such as scpi_dvfs_info() / cpufreq init call this per CPU, so
the leak accumulates over time.

Save the domain id, of_node_put(clkspec.np), then return the saved value.
