iwlwifi: add missing type declaration

The iwl-debug.h header relies in implicit inclusion of linux/device.h and
we get a lot of warnings without that:

drivers/net/wireless/intel/iwlwifi/iwl-debug.h:44:23: error: 'struct device' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
 void __iwl_err(struct device *dev, bool rfkill_prefix, bool only_trace,
                       ^~~~~~

                 from drivers/net/wireless/intel/iwlwifi/iwl-eeprom-read.c:68:

                                                                                                                                                                                                                                                                                                                                                            ^
In file included from drivers/net/wireless/intel/iwlwifi/iwl-eeprom-read.c:67:0:
drivers/net/wireless/intel/iwlwifi/iwl-debug.h:44:6: note: expected 'struct device *' but argument is of type 'struct device *'
 void __iwl_err(struct device *dev, bool rfkill_prefix, bool only_trace,
      ^~~~~~~~~

The easiest workaround is to just declare 'struct device' before its first use,
rather than including the entire header file.
