Ian Abbott 0f5eb15459 fpga: region: release of_parse_phandle nodes after use
Both fpga_region_get_manager() and fpga_region_get_bridges() call
of_parse_phandle(), but nothing calls of_node_put() on the returned
struct device_node pointers.  Make sure to do that to stop their
reference counters getting out of whack.

Fixes: 0fa20cdfcc1f ("fpga: fpga-region: device tree control for FPGA")
