powerpc/mpc5xxx: Add missing fwnode_handle_put()

Browse Source 
[ Upstream commit b9bbbf4979 ]

In mpc5xxx_fwnode_get_bus_frequency(), we should add
fwnode_handle_put() when break out of the iteration
fwnode_for_each_parent_node() as it will automatically
increase and decrease the refcounter.

Fixes: de06fba62a ("powerpc/mpc5xxx: Switch mpc5xxx_get_bus_frequency() to use fwnode")
