Modify the power control code and vbif_bw governor
to allow dynamic AB votes to be set with each GPU
IB vote. As a placeholder set a static AB vote of
one fourth the IB vote.

This governor should be used by KGSL driver to vote for msm bus
bandwidth using devbw devices.
KGSL driver needs to register a callback function that returns
required IB value, and call devfreq_vbif_update_bw() function
any time it want to vote for bus bandwidth.

The existing devfreq governor_msm_adreno_tz supports both GPU DCVS and BMC
(Bus Modification Calculation) at the same time. This change splits BMC
code into a new governor_gpubw_mon.

The devfreq infrastructure has several bugs and general design flaws
with private governor data support. As a workaround the msm-adreno-tz
governor gets it's private data from the device driver by doing a
container_of on the dev_profile registered by the device driver.

Some platforms require new CMD IDs to support tz functionality.
Check the ID supported and call the appropriate scm call.

Use the vbif performance counter which counts bus busy cycles
to determine the requested bus bandwidth vote at a given
GPU frequency.

be based on devfreq.
