Added Sound Control version 1.

pick fix
TWL6040_RAMP_ZERO is only used for changing the headset volume.
The headset power mode is kept on high-performance while no headset is
plugged in and changed to the user defined mode as soon as a headset
is plugged in.

fix
If headphones are (un)plugged and the codec driver has not been initialized
yet (can happen during boot with attached headphones), the headset power
mode is not changed.
Properly apply volume boost on volume change.
sched: don't call task_group() many times in set_task_rq()

It improves perfomance, especially if autogroup enabled.

The size of set_task_rq() was 0x180 and now it is 0xa0.

ondemand: cpuidle detection
I found a problem with the ondemand governor while in earlysuspend
suspend mode (ondemand keeping the freq close to the max at all times
despite near 0% load). The problem is that the cpu starts to go in
long cpuidle cycles, a sampling_rate of 10000 (usec) is applied only
once in a while and the real sampling_rate becomes 1 second (or more).

So when a wakeup happens we return to the 10000usec sampling rate. The
ondemand sees lots of activity after the wakeup but those "loads" must
be adjusted down if the previous wall_time delta was huge and the
current one is tiny. We're too close to long cpuidle to worry about
the cpu freq anyway and it may be just a jitter load that if we take
into account without adjusting it down, will lead to the next long
cpuidle to be entered at the max freq again, and this repeats forever.

So my solution is to tweak the ondemand to scale down the "load"
according to the decrease in the wall_time delta ratio
(deep_sleep_ratio variable). This allows the CPU to stay at the lowest
freq during the deep sleeps even when the ondemand governor is enabled
and the sampling_rate is set to 10000. (setting the sampling_rate to
values >100000 would also tend to hide the problem but it'd screw the
interactive behavior by running at the lowest frequency for too long
during interactive usage)

During interactive usage with the screen on (not in earlysuspend
mode), or during playback or voip with screen off the deep_sleep_rate
is set to 1 practically all the time so it won't alter the behavior of
the ondemand governor unless the system is very idle (and in turn when
we want it to stay at low freq).
