iwlwifi: move agn only eeprom functions to separate file
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. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

/************************** EEPROM BANDS ****************************
|
||||
*
|
||||
* 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
|
||||
* given channel. We have to have two separate maps as there is channel
|
||||
* 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
|
||||
* be able to associate or transmit any frames on that
|
||||
* channel. There is no corresponding channel information for that
|
||||
* entry.
