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.
