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.
