HID: uhid: introduce user-space I/O driver support for HID
This adds a dummy driver that will support user-space I/O drivers for the
HID subsystem. This allows to write transport-level drivers like USB-HID
and Bluetooth-HID in user-space.
Low-Energy Bluetooth needs this to feed HID data that is parsed in
user-space back into the kernel.

+ Say Y here if you want to provide HID I/O Drivers from user-space.
+ This allows to write I/O drivers in user-space and feed the data from
+ the device into the kernel. The kernel parses the HID reports, loads the
+ corresponding HID Device Driver or provides input devices on top of your
+ user-space device.
+
+ This driver cannot be used to parse HID-reports in user-space and write
+ special HID-drivers. You should use hidraw for that.
+ Instead, this driver allows to write the transport-layer driver in
+ user-space like USB-HID and Bluetooth-HID do in kernel-space.
+
+ If unsure, say N.
+
+ To compile this driver as a module, choose M here: the
+ module will be called uhid.
