Subject: [054/121] iwl4965: set power mode early

3.2.51-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Stanislaw Gruszka <sgruszka@...hat.com>

commit eca396d7a5bdcc1fd67b1b12f737c213ac78a6f4 upstream.

If device was put into a sleep and system was restarted or module
reloaded, we have to wake device up before sending other commands.
Otherwise it will fail to start with Microcode error.
