For BT/WiFi combo devices, need longer tx stuck queue
timer, so those devices won't reload firmware too often.

Some of the functions in iwl-eeprom.c file are for agn devices only,
Those functions do not have to be part of iwlcore.ko, so move those
to iwl-agn-eeprom.c file.

+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a

+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware. This means that
+ * while the system can tune and receive on a given channel, it may not
