ethernet: eqos: fix hang while changing MAC address

Issue: Interface need to bring down to change the
MAC address. Once the interface is down all the
clocks to EQOS IP will be removed for power saving
purpose. At this time if we are trying to access
IP registers it will result in hang.

And one more point is updating HW registers for
updating MAC address is unncessary because the
same will be done during interface bring up.

Fix: Don't access hardware registers once the
interface is down.
