iwlagn: remove old EEPROM TX power reading

Browse Source 
This removes the old TX power reading code, it isn't
necessary since the new code is able to read all the
various EEPROM layouts due to relying on information
contained in the EEPROM.

/************************** 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.
