Add infrastructure to allow multiple ICP subdevices to co-exist
with each subdevice exposed to UMD individually. All operations
including ioctl on each subdevice are discrete from another's. Add
a new private field in node structure to point to which subdev
the node belongs to. Add a new ICP1 device type and expose the type
associated with ICP1 to userspace for identifying the second ICP.
Each subdevice's unique name is derived from "cam-icp". The name is
then appended with a cell-index if it exists. If there are multiple
nodes in DTSI to be probed, each node must contain cell-index to
differentiate them.
For each subdevice, it is expected to have a unique node in DTSI
with unique compatible string to probe the sd during boottime.

In subdev close call if CRM is still active wait for shutdown
from CRM [media device]. Remove subdevice check for active
handles, shutdown to happen irrespective of any active context.
If CRM is not active, subdevice shutdown should ensure there is
no access to kernel allocated buffers since at this point
memmgr is de-initialized.
As part of ICP close, remove usage of HFI queues, trigger PIL
to transfer FW memory ownership back to HLOS and power off ICP.

when provider crash occurred, there was a CSID lane overflow
observed due to shutdown sequence from CRM(sensor, csid, csiphy).
To fix the issue need to change the shutdown sequence
(csid, sensor, csiphy).
This change will update the devices sequence in order while registering
and close the sequence accordingly.

Some usecases need more than the original max depth of 20 for ICP
contexts. Accommodate these usecases by increasing the max request
depth only for ICP.
