Subject: [PATCH net-master] net: phy: dp83848: Add the TI TLK05/06 PHY ID

Add the TLK05/06 PHY ID to the DP83848 driver.  The TI website indicates
that the DP83822 device is a drop in replacement for the TLK05 device
but the TLK device does not have WoL support.  The TLK device is
register compatible to the DP83848 and the DP83848 does not support WoL
either.  So this PHY can be associated with the DP83848 driver.

The initial TLKx PHY ID in the driver is a legacy ID and the public data
sheet indicates a new PHY ID.  So not to break any kernels out there
both IDs will continue to be supported in this driver.
