In the data path configuration, one of the parameters is the channel.  We
have been setting it to wl->channel, which is not correct in this case.  This
channel has nothing to do with the channel we're currently tuned to, since it
is only used for calibration during this phase.  Hardcoded the channel to 1,
according to the reference driver.

The receive descriptor ops that are currently marked as being for

receive descriptor ops marked as 8366 are only used on 8366 when an
AP firmware image is in use.

Rename the receive descriptor ops to reflect this, use the STA ops
unconditionally if the firmware image loaded reported the STA ready
code, and rename the mwl8k_device_info::rxd_ops member to ap_rxd_ops
to indicate that it should only be used if we are running on AP
