====================
DP83869 Enhancements

These are improvements to the DP83869 Ethernet PHY driver.  OP-mode and port
mirroring may be strapped on the device but the software only retrives these
settings from the device tree.  Reading the straps and initializing the
associated stored variables so when setting the PHY up and down the PHY's
configuration values will be retained.
