HID: sensors: introduce sensor framework
Adding processing for HID Sensor usage table as defined by
HID 1.12, Request #: HUTRR39, dated 05 May, 2011.
This driver uses HID driver framework to register, send and
receive events.
This uses MFD framework, so that actual processing for a
specific usage id can be done in a different driver. For
example an accelerometer driver can be a separate driver and
use the interface provided by this driver to register for
events.

+ Support for HID Sensor framework. This creates a MFD instance
+ for a sensor hub and identifies all the sensors connected to it.
+ Each sensor is registered as a MFD cell, so that sensor specific
+ processing can be done in a separate driver. Each sensor
+ drivers can use the service provided by this driver to register
+ for events and handle data streams. Each sensor driver can format
+ data and present to user mode using input or IIO interface.
