net/vsc9953: Add driver for Vitesse VSC9953 L2 Switch IP

This patch adds a driver for VSC9953 L2 Switch. This Vitesse IP
is integrated in Freescale T1040 and T1020 SoCs.
The L2 switch has 10 Ethernet ports: 2 internal fixed-links
(ports 8 and 9) at 2.5 Gbps and and 8 external ports at 1 Gbps.
The external ports may be connected to PHYs over QSGMII and SGMII.

Commands have also been added to enable/disable a port and to
check a port's link speed, duplexity and status. The commands are:

ethsw port <port_nr> enable|disable - enable/disable an l2 switch port
ethsw port <port_nr> show - show an l2 switch port's configuration

port_nr=0..9; use "all" for all ports

For more detailse please see doc/README.t1040-l2switch

This file contains information for VSC9953, a Vitesse L2 Switch IP
which is integrated in the T1040/T1020 Freescale SoCs.
About Device:
VSC9953 is an 8-port Gigabit Ethernet switch supports the following features:
- 8192 MAC addresses
- Static Address provisioning
- Dynamic learning of MAC addresses and aging
- 4096 VLANs
- Independent and shared VLAN learning (IVL, SVL)
- Policing with storm control and MC/BC protection
- IPv4 and IPv6 multicast
- Jumbo frames (9.6 KB)
- Access Control List
- VLAN editing, translation and remarking
- RMON counters per port
Switch interfaces:
- 8 Gigabit switch ports (ports 0 to 7) are external and are connected to external PHYs
- 2 switch ports (ports 8 and 9) of 2.5 G are connected (fixed links)
to FMan ports (FM1@DTSEC1 and FM1@DTSEC2)
Commands Overview:
Commands supported
- enable/disable a port
- check a port's link speed, duplexity and status.
Commands syntax
ethsw port <port_nr> enable|disable - enable/disable an l2 switch port
ethsw port <port_nr> show - show an l2 switch port's configuration
port_nr=0..9; use "all" for all ports
=> ethsw port all show
Port Status Link Speed Duplex
0 enabled down 10 half
1 enabled down 10 half
2 enabled down 10 half
3 enabled up 1000 full
4 disabled down - half
5 disabled down - half
6 disabled down - half
7 disabled down - half
8 enabled up 2500 full
