[oe] [meta-oe][warrior][thud][PATCH] cpupower: remove LIC_FILES_CHKSUM

[Nicolas Dechesne]

cpupower is a 'special' recipe since it does "inherit kernelsrc" ,
which essentially means that it doesn't have its own sources, but
reuse the kernel source tree, from virtual/kernel recipe. As such,
checking the license file in cpupower recipe does not seem relevant,
since it does not fetch anything (kernelsrc has "deltask do_fetch")
and the fetching is deferred to the virtual/kernel recipe.

so we are basically checking the COPYING file twice. If there was any
license issue, it would have been caught by virtual/kernel recipe
already.

Hence we remove LIC_FILES_CHKSUM like it is done for perf recipe in
OE-core in meta/recipes-kernel/perf/perf.bb.

It has the nice side effect that BSP layers can use different kernel
versions without worrying about any LICENSE checksum changes in
between kernel versions.

Armin, for our use cases (at least) this is a bug fix, since we use
different kernel versions in our BSP layers.. I am hoping you will
agree to merge it is -stable branches. If you can apply to warrior and thud
where it applies cleanly that would be really nice. It won't apply on sumo, 
i can send another patch later for sumo.
