> When not using DM_ETH, these PHY settings are programmed with default
> values hardcoded into the driver.  When using DM_ETH, they should come
> from the device tree.  However, if the device tree does not have the
> properties, the driver will silent use -1.  Which is entirely out of range,
> programs nonsense into the PHY's registers, and does not work.
> 
> Change this to use the same defaults as non-DM_ETH if the device tree is
> lacking the properties.
> 
> As an alternative, the kernel driver for the phy will display an error message
> and fail if the device tree is lacking.
