cpufreq: intelliactive: initial coding and introduction!

intelliactive is based on Latest Google Interactive cpufreq governor from
Google.  The original Interactive provides smooth UI operations but suffers
slight battery drain due to its aggressive policies.  Intelliactive is an
improvement built on top of it.

It has the following enhancements added:
1. self-boost capability from input drivers (no need for PowerHAL assist)
2. two phase scheduling (idle/busy phases to prevent from jumping directly to
   max freq
3. Checks for offline cpus and short circuits some unnecessary checks to
   improve code execution paths
4. removed trace calls

Revert "HTC DTS: fix a few warnings"

Wow HTC... Qualcomm already using non-standard DTS, you now added MORE
non-standard DTS on top!  Good job :(
