The camnoc max needed flag is stored for each tree node and
parsed once per level. Fix parsing of camnoc max needed flag.
Improve cpas logging. Part of this change fixes issue introduced
in: commit d099238a67 ("msm: camera: cpas: Update bus node
level parsing logic").

Currently, the order in which we read the camera bus nodes
is dependent of the order camera device tree is laid out,
which causes issues if the arragement is changed. Update DT
parsing logic to read node levels independent of arrangement.

While searchig node by name, it is walking outside of
parent node looking for the given node name. Call
of_get_child_by_name instead, so that it looks within the

To support external module compilation on Waipio, camera dt-bindings header
files need to be moved out of kernel SI and into the camera-kernel vendor SI.
This is to maintain seperation between the two SI's.

If MP limit fuse feature is enabled in DTSI then
read the fuse register to get information about maximum
allowed resolution. According to that restrict CSID acquire.
Also if only DTSI based max_width is enabled then restrict acquire
with maximum allowed width.

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.

For some targets, it is needed to vote for camnoc clock
as there is no CAMNOC AXI clock source in camera domain.
Voting is done with the bus drivers and it calcultates
the clock rate.
This change adds support for camnoc based voting.
