Enable registration of suspend_ops with kernel. This will enable
platform specific low power states based on odm query.

We implement suspend_ops->valid, suspend_ops->begin,
suspend_ops->enter and suspend_ops->end.

For suspend_ops->begin :
Check if CPU1 is in reset or not.
If not, reset it and maintain this state.

For suspend_ops->end :
Check if CPU1 was reseted by suspend_ops->begin.
If yes, take it out of reset.
For harmony board, add a timed wake lock as a WAR.

For suspend_ops->enter :
Do a odm query for lowest power state.
Call the appropriate low power state (LP1/LP0)
routine based on SOC type.

occassionally, the keyboard stops functioning after the system resumes from
suspend state; this may be due to a failure enabling keyboard scanning
mode during suspend.

disable suspend/resume calls from nvec keyboard driver until a solution
for this problem is resolved (e.g., converting nvec to a bus).

Bug 653500
This is an issue in RM transport.
This is because of sleep time when the buffer is not ready to send msg.
The sleep of 1msec is taking 10 to 20msec time as linux jiffy time is 10msec.
This fixed by using the polling for one jiffy time and using sleep afterwards.

Moved EMC DFS low corner back to 50MHz (from 18MHz - affects LPDDR2
platforms). This is done since new AudioMixer unable to reach 18MHz
LC - optimization is in progress (bug 654473).
