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.
