The current CPUfreq patcheset has dependencies TI's shared resource
framework (SRF), which in turn depends on the new OMAP PM layer.
Neither of which are included in the current PM branch.

My current plan is to get off-mode in suspend and dynamic idle
stabilized along with CPUidle before integrating the new PM layer and
SRF.
