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.
