net: phy: dp83867: Check if the phy is in an internal testing mode

The DP83867 seems to be always in an internal mode on our Board.
This mode can cause connection problems. We disable this mode.

Unfortunately, Register 0x31 Bit 7 is not documented and marked as reserved.
If Bit 7 is set, phy is in the internal testing mode.
