iwlwifi: change struct iwl_fw
Change iwl_fw struct to hold an array of fw_img instead of three separated instances. Change fw_img to hold an array of fw_desc instead of two separate descriptors for instructions and data. Change load_given_ucode, load_section, verification functions etc. to support this structure.
