iwlwifi: fix FAT channel config for 5000 series
The test to find out if we have FAT channels do not consider that the value of regulatory_bands for the 5000 series is larger than its eeprom size. Using the eeprom size is strange in itself. Use a new EEPROM_REGULATORY_BAND_NO_FAT to indicate no FAT support and test for that explicitly.
