Changes in v2:
- Add Yilun tag
- Add missing license to altera-hps2fpga-bridge.yaml
- Drop reg as required property from altera-fpga2sdram-bridge.yaml
- Align file names with compatible string
- Drop | from description entry because no need to preserve formatting
- Keep only one example in altr,socfpga-hps2fpga-bridge.yaml

Either I misunderstood previous messages or something is still wrong.
One message said: always unit address, so there will be no
fpga-bridge-1. This means "?" is not correct.
Other message was saying "reg" is not required in one of the bindings,
thus "fpga-bridge-1" is reasonable if there are more than one bridge
(which was already said as possibility?).
