Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx28 client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.

The bootloader seeks for this alias and adds "mac-address" and "local-mac-address" properties to the aliased node. This fixes issues with FEC having NULL MAC address when update_fec_mac_prop() wasn't called. And not all boards call update_fec_mac_prop() .
