Subject: [PATCH] eisa: address link failure

From: Arnd Bergmann <arnd@...db.de>

The devlist.h file is generated at build time but is not an object file,
so linking fails, at least in some configurations:

ld.lld-21: error: vmlinux.a(drivers/eisa/devlist.h): not an ELF file

Make this an extra-y instead of obj-y target in Kbuild.

Fixes: dd09eb0e2cc4 ("EISA: Increase length of device names")
