net: defxx: constify eisa_device_id

ArvindYadavCs · davem330 · commit 46d9ceaad0b0 · 2017-08-19T17:13:41.000-07:00
eisa_device_id are not supposed to change at runtime. All functions
working with eisa_device_id provided by &lt;linux/eisa.h&gt; work with
const eisa_device_id. So mark the non-const structs as const.
