[PATCH 17/17] of_firmware: Fix handling of firmware-name property

[Sascha Hauer]

The fpga-region binding states that the firmware-name property must be
in the same node as the fpga-region compatible, so checking for this
compatible when walking up the parents is wrong. Instead, only test for
it in the target node. Also, when the current node is not a fpga-region
we must return successfully.
