Daniel Golle 399d5cf532 mac80211: rt2x00: import upstream changes and rebase our patches
Some of our local patches have been accepted upstream. And there are
some more relevant changes (mostly for rt2800usb). Import them and
rebase our remaining local patches on top.

Subject: [PATCH 01/19] rt2x00: avoid introducing a USB dependency in the
rt2x00lib module
As reported by Felix:
Though protected by an ifdef, introducing an usb symbol dependency in
the rt2x00lib module is a major inconvenience for distributions that
package kernel modules split into individual packages.
Get rid of this unnecessary dependency by calling the usb related
function from a more suitable place.
