rt2x00: Rework rt61 antenna selection.

This patch changes rt61 antenna selection again. It helps at least with the
rt61 pci card in my box, I hope I haven't broken behaviour on other RF chips.
RF 2529 antenna setup is incomplete, we need to at code for diversity when we
figure out how it is done properly.
