msm: camera: icp: Dynamic clock bandwidth support
Add support for IPE and BPS dynamic clock
and bandwidth for realtime streams. Add support
to set clock and bandwidth based on user request
for debug purpose. Following command is used to
provide clock rate from user.
echo "clk rate" > /sys/kernel/debug/camera_icp/icp_debug_clk
