Add TPG mux select logic in CPAS. To select form which TPG CSID should
get the data, TPG_MUX_SEL register has to be programmed. This change
adds the logic to write this register on CPAS driver.

This change creates a sysfs entry(subparts_info) which
has info about number of IFEs, IFE-LITEs, SFEs & CUSTOM,
whose values are populated in their respective drivers.
Also, validates whether a particular IFE, SFE and CUSTOM
is supported or not. Based on this, probe of IFE, SFE and
CUSTOM drivers will happen accordingly.

In CPAS v980, CAMNOC is split into RT and NRT. Camnoc RT and NRT each
has separate register base. Camnoc RT is used by TFE, IFE lite, RT CDM.
Camnoc NRT is used by OFE, IPE, ICP, JPEG, NRT CDM. There are also two
IRQ lines for CPAS: RT and NRT IRQs.
Add CPASTOP SBM IRQ for RT/NRT, static QOS NOC settings for RT/NRT,
Cesta, and others in the header file for v980. CPAS registers two IRQ
lines and handles the incoming (RT/NRT) IRQs based on the IRQ data for
each IRQ. CPAS SOC looks for IRQ identifier property in CPAS node DT
to classify the IRQ type.
Global Camnoc info variable and qchannel variable now contain separate
info for RT/NRT or combined info.
Add NRT reg base for camnoc NRT base. Add TFE UBWC Encode error.

On chipsets having cesta hw block support, for cesta supported clks
clk frequency can be changed during veritcal blanking based on
CSID DRV events. For this to happen, camera clients need to setup
high and low clock votes through hw clients. Use corresponding clk,
crm APIs to setup high, low clk frquencies and do channel switch
to apply newly set rates. Clients can also set clk frequency through
sw client which will set the floor. This feature helps in saving
power for usecases where vertical blanking is high such as
Fast Shutter usecase.

For some chipsets, qchannel handshake needs icp clk to be
enabled. Add support to enable icp clk while qchannel
handshake by adding as optional clk in cpas node. Whether
to enable icp clk or not is controlled through workaround
list populated for each chipset.
Add mechanism to retry qchannel acceptance if the first
auto try has failed, by explicity writing 0x1 to qchannel
ctrl register. This will bring back qchannel to good state.

Currently, camnoc buffer fill level register offsets are part
of cpas monitoring. Register offsets keep changing between
targets which would bring more conditionals. Make cpas monitoring
generic by moving register offsets to header. Also, the reg values
will be read in a buffer, and it can be controlled what offset
needs to be read, by changing status in header to be enable/disable.
Also, move camnoc fill level printing to CPAS for when we need only
buffer fill info.
