stmmac: update the Doc and Version (PTP+SGMII) 

This patch updates the stmmac.txt file adding information related to the PTP
and SGMII/RGMII supports.

Also the patch updates the driver version to: March_2013.

@ -326,6 +326,35 @@ To enter in Tx LPI mode the driver needs to have a software timer
that enable and disable the LPI mode when there is nothing to be
transmitted.
7) TODO:
7) Extended descriptors
The extended descriptors give us information about the receive Ethernet payload
when it is carrying PTP packets or TCP/UDP/ICMP over IP.
These are not available on GMAC Synopsys chips older than the 3.50.
At probe time the driver will decide if these can be actually used.
This support also is mandatory for PTPv2 because the extra descriptors 6 and 7
are used for saving the hardware timestamps.
8) Precision Time Protocol (PTP)
The driver supports the IEEE 1588-2002, Precision Time Protocol (PTP),
which enables precise synchronization of clocks in measurement and
control systems implemented with technologies such as network
communication.
In addition to the basic timestamp features mentioned in IEEE 1588-2002
Timestamps, new GMAC cores support the advanced timestamp features.
IEEE 1588-2008 that can be enabled when configure the Kernel.
9) SGMII/RGMII supports
New GMAC devices provide own way to manage RGMII/SGMII.
This information is available at run-time by looking at the
HW capability register. This means that the stmmac can manage
auto-negotiation and link status w/o using the PHYLIB stuff
In fact, the HW provides a subset of extended registers to
restart the ANE, verify Full/Half duplex mode and Speed.
Also thanks to these registers it is possible to look at the
Auto-negotiated Link Parter Ability.
10) TODO:
o XGMAC is not supported.
o Add the PTP - precision time protocol
o Complete the TBI & RTBI support.
o extened VLAN support for 3.70a SYNP GMAC.
