msm: camera: cpas: Add more debug information in cpas dump

Enhance cpas state dump to get more information about
bandwidth and clock status. This additional state dump
can be enabled using debugfs.

adb shell "echo 1 > /sys/kernel/debug/camera_cpas/full_state_dump"

Traverse through all bw tree nodes and print info in each node.
Print current clk frequencies of all clocks that cpas enables.
Read rpmh bcm status registers to understand mmnoc clk freq.
Add cpas monitor to save important info whenever clients
notify with an event. This monitor info is printed in cpas
state dump.
