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.

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
