Add support for VSC8531_02 PHY ID.
Also provide an option to tune RGMII delay value via devicetree.
The default delays are retained in the driver.

v2 changes:
- Added patch to use a common vendor phy id match
- Removed dt include header patch because delays should be specied in
ps, not register values
- Updated DT binding description and commit for optional delay tuning to
be clearer on the precedence
- Updated dt property name to include vendor instead of phy device name
- Switch both VSC8531 and VSC8531-02 to use exact phy id match as they
share the same model number
- Ensure RCT
- Improve optional property read
