[U-Boot] [PATCH v2] tsec: do not print Speed: if using netconsole

[Ed Swarthout]

CONFIG_NETCONSOLE on the p2020ds is functional with the tsec driver.  
But the printf in adjust_link() which is called by startup_tsec()
called by tsec_init() in tsec.c is making it impossible to use.

For example typing 12345 on the netconsole causes the message to be
printed for every character:

=> Speed: 1000, full duplex
1Speed: 1000, full duplex
2Speed: 1000, full duplex
3Speed: 1000, full duplex
4Speed: 1000, full duplex
5Speed: 1000, full duplex

Based on a suggestion from Peter Tyser, check env and only disable if
currently using netconsole.
