net: phy: dp83td510: Add config phase

Add a config phase for the Texas Instruments DP83TD510E ethernet PHY

The config phase currently sets the following properties from the
device tree:
  * RMII / RGMII mode (note : RMII master / slave can only be set
    by straps and cannot be changed at runtime)
  * RGMII delays. These delays can be enabled on the phy side, only
    as a boolean. Delays are enabled if phy-mode is rgmii-id, or
    rgmii-[rx|tx]id which enables only the corresponding delay.
  * In case another mode is encountered, do nothing and return
    success (keep old behavior)

Note on RCSR: unlike the DP83822, on the DS83TD510E both
delays are active-high (ie, rgmii internal delays are enabled
when the corresponding bit is set to 1 in the configuration
register).
