video: driver: debugfs update for clockrate,bandwidth setting

Browse Source 
/d/msm_vidc/core_clock_voting will modify only clock rate
and not ddr and llc bandwidth.
example usage:
adb shell "echo 444000000 > /d/msm_vidc/core_clock_voting".

introduction of /d/msm_vidc/ddr_bw and /d/msm_vidc/llcc_bw
which will modify ddr and llc bandwidth respectively.
example usage:
adb shell "echo 5000000 > /d/msm_vidc/ddr_bw_kbps".
adb shell "echo 7000000 > /d/msm_vidc/llc_bw_kbps".
