Johann Fischer 8999c30cee usb: hid: remove get_protocol/set_protocol from USB HID class API
The USB HID class API offers the possibility to register callbacks
for Get/SetIdle, Get/SetProtocol to the application.
Rules for these callbacks are neither obvious nor documented.

This patch remove this possibility to register Get/SetProtocol
and Get/SetIdle callbacks for the following reasons:

The possibility to call unknown application code while processing
control requests should be avoided or reduced to a minimum.

The Get/SetProtocol callbacks are redundant and do not provide any
additional value since the way to inform the application
about the change of the protocol exists via the callback
hid_protocol_cb_t protocol_change.

The core provides implementation to handle Get/SetIdle requests and
on idle reports. If this is not suitable in any way then the application
should implement everything itself.
