HID: Add Support for Setting and Getting Feature Reports from hidraw
Per the HID Specification, Feature reports must be sent and received on
the Configuration endpoint (EP 0) through the Set_Report/Get_Report
interfaces. This patch adds two ioctls to hidraw to set and get feature
reports to and from the device. Modifications were made to hidraw and
usbhid.
New hidraw ioctls:
HIDIOCSFEATURE - Perform a Set_Report transfer of a Feature report.
HIDIOCGFEATURE - Perform a Get_Report transfer of a Feature report.
