[PATCH 0/4][KERNEL] more bsp cleanup and new power/intel feature

[tom.zanussi]

From: Tom Zanussi <tom.zanussi@intel.com>

This patchset adds a new power/intel feature containing power-related
config items for intel bsps and initially makes sugarbay and crownbay
use it.

It also removes the igb feature from common-pc-64, which shouldn't
be there and was responsible for Yocto bug #1188.

Fixes [YOCTO #1188]

Please pull into linux-yocto-3.0 and linux-yocto-dev.

Looks good. Do you agree that this would be part
of any 1.1 point release as well, or is this purely a
1.2/cleanup activity ? If it's the latter, I need to wait
for the 1.1 sustaining kernel to be created.

I think this is all purely 1.2/cleanup.  It does fix a bug, but not a
serious enough to make it into a point release, IMHO.
