Changes in v2:
- Remove binding ti,tx-amplitude-100base-tx-millivolt from ti,dp83822.yaml
- Add binding tx-amplitude-100base-tx-gain-milli to ethernet-phy.yaml
- Add helper to get tx amplitude gain from DT
- Link to v1: https://lore.kernel.org/r/20250113-dp83822-tx-swing-v1-0-7ed5a9d80010@liebherr.com
