barebox: move fan start to before ^C check

	* this code also sets fan freq, so if developer presses
		^C then types boot, it will skip fan freq setting,
		and whine when linux starts fan
	* went back and forth on where to place it with Daniel,
		and we decided the risk was low here.
	* also remove -v so it doesn't slow down boot much
