Revert "devfreq: Do not allow tunable updates when device is suspended" 



This reverts commit efff55e2.

When device is suspended setting tunnable is not allowed,
now governor changed to handle the suspend state of device.

Allow configuring tunable when device is in suspend state,
revert changing the code which is not allowing to set tunables.
