Changes in v3:
- Improve regex to cover also nodes out of bus

Keeping Krzysztof's tag which I got in v1. Feel free to reject if you
see any issue there.

(no changes since v2)

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
