Add cpas interface to allow clients or usecase to select
different QoS settings based on requirement. Selection
API must be called before camera hw powers up.

In many error cases it is required to know the
bandwidth applied on axi ports and camnoc axi
clock rate values. Added cpas api to print the
current axi bus votes, camnoc axi clock and ahb
vote level.This api can be called for isp errors
such as bus overflow, pxl overflow cases.
On RDI overflow printing last applied IFE clock,
dumping the CAMNOC fill-level registers to know
the pending and queued transactions, SOF EPOCH
and EOF timing to know exactly at what time the
RDI overflow came, Width and height of specific
Write master.

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.

Add support for disabling bus scaling by moving bus driver
references from cpas to cam utils. The references can be
switched based on compile time flags in defconfig. Also, add
interconnect support which has bw voting based on source and
destination bus IDs.

This change scales BW voting with src clock voltage corner.
Adds a debugfs to disable this scaling.

As part of cpas start, all drivers will now request for
LOW_SVS as opposed to SVS. The drivers also scale the AHB
vote based on the corresponding HW's src clk voltage.
