il3945_txpower_set_from_eeprom - Set channel power info based on EEPROM

Second pass (during init) to set up il->channel_info

Set up Tx-power settings in our channel info database for each VALID (for this geo/SKU) channel, at all Tx data rates, based on eeprom values and current temperature.

Since this is based on current temperature (at init time), these values may not be valid for very long, but it gives us a starting/default point, and allows us to active (i.e. using Tx) scan.

This does not write values to NIC, just sets up our internal table.
