This fixes an oops when programs access ethtool methods, especially
wrn_get_drvinfo. It can be reproduced by a simple run of "irqbalance",
which I never did in my development machine.

- platform_data is now wrn_drvdata, fix accordingly

- include ../spec-nic.h to have wrn_drvdata available

- #if 0 irq requesting and other detatils

- some printk statements end other irrelevant stuff

The files come from commit "wr-switch-sw-v3.0" of wr-switch-sw
project.  They are straight copies from kernel/wr_nic (there) to
kernel/wr_nic (here).  Three have not been copied, as they don't apply
here: dmtd.c, pps.c, module.c

Later patches will customize them to they compile in this environment.
Note that as of this commit they are not compiled by the Mafile yet,
this is only a verbatim copy to easily keep track of differences.
