[PATCH v2] firmware/Makefile: force recompilation if makefile changes

[Luis R. Rodriguez]

If you modify the target asm we currently do not force the
recompilation of the firmware files. The target asm is in
the firmware/Makefile, peg this file as a dependency to
require re-compilation of firmware targets when the asm
changes.

Michal,

I had this patch as part of my linker table series [0] but have split it
off as its a small atomic separate change and can go in separately. Greg
prefers this be reviewed by the kbuild tree so sending it your way.
This v2 has no modifications, just resending it to the kbuild tree.
