fsl/fman: Add FMan MAC support

Add the Data Path Acceleration Architecture Frame Manger MAC support.
This patch adds The FMan MAC configuration, initialization and
runtime control routines.
This patch contains support for these types of MACs:
	- dTSEC: Three speed Ethernet controller (10/100/1000 Mbps)
	- tGEC: 10G Ethernet controller (10 Gbps)
	- mEMAC: Multi-rate Ethernet MAC (10/100/1000/10000 Mbps)
Different FMan revisions have different type and number of MACs.
