defconfig: turn on SCHED_MC for some MSM targets

Browse Source 
Currently CPUs that have entered nohz idle mode are not being woken
up to perform load balancing. Turning on SCHED_MC will fix that, and
will also cause CPUs to show up at the correct level of scheduling
domain (MC).

SCHED_MC would normally also cause SD_SHARE_PACKAGE_RESOURCES to be
turned on at the MC level as well, causing a task to be migrated to
an idle CPU when the task is woken up. Previous modifications to
SD_SHARE_PACKAGE_RESOURCES however have restricted its effect
to tasks that have the PF_WAKE_ON_IDLE flag set.

Certain target configurations (msm7627a*, msm8660*) are being left
out until they are verified with SCHED_MC.
