Dan Carpenter 1f1e70efe5 fsl/fman: fix a leak in tgec_free()
We set "tgec->cfg" to NULL before passing it to kfree().  There is no
need to set it to NULL at all.  Let's just delete it.

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.
