ath9k_hw_rfattach() was just calling a helper and this helper was doing nothing for single-chip devices, and for non single-chip devices it is just allocating memory for banks to program the RF registers at a later time. Simplify this by having the hw initialization call the rf bank allocation directly for external radios. Also, propagate an -ENOMEM properly now upon failure. Signed-off-by: Luis R.
