Hareesh Gundu af88f06094 devfreq: Add support to configure bus dcvs sampling interval
Add support to configure bus dcvs sampling interval through the
sysfs entry. Also expose cur_ab vote value to sysfs.

$ echo 25000 > /sys/class/devfreq/soc:qcom,kgsl-busmon/sampling_interval
$ cat /sys/class/devfreq/soc:qcom,kgsl-busmon/cur_ab .
