net: phy: dp83867: io impedance is not dependent on RGMII delay

Browse Source 
Based on commit 27708eb5481b ("net: phy: dp83867: IO impedance is not
dependent on RGMII delay") of mainline linux kernel.

The driver would only set the IO impedance value when RGMII internal delays
were enabled.  There is no reason for this.  Move the IO impedance block
out of the RGMII delay block.
