Simply always print the HID++ version on hidpp_root_get_protocol_version
success.
This also fixes the version not being printed when a HID++ device
connected through a receiver is already connected when the hidpp driver
is loaded.

Similar to commit edfc3722cfef ("HID: quirks: Fix keyboard + touchpad on
Toshiba Click Mini not working"), the Lenovo Miix 630 has a combo
keyboard/touchpad device with vid:pid of 04F3:0400, which is shared with
Elan touchpads. The combo on the Miix 630 has an ACPI id of QTEC0001,
which is not claimed by the elan_i2c driver, so key on that similar to
what was done for the Toshiba Click Mini.

ISH clients don't need to access any field of struct ishtp_cl_device. To
avoid this create an interface functions instead where it is required.
In the case of ishtp_cl_allocate(), modify the parameters so that the
clients don't have to dereference.
Clients can also use tracing, here a new interface is added to get the
common trace function pointer, instead of direct call.
The new interface functions defined in one external header file, named
intel-ish-client-if.h. This is the only header files all ISHTP clients
must include.

Currently we depend on the guid check in ishtp_cl_driver.probe to match
the device and driver. However Linux device core first calls the match()
callback to decide the matching of driver and device, and then does some
preparation before calling the driver probe function. If we return error
in the driver probe, it needs to tear down all the preparation work and
retry with next driver.
Adding the match callback can avoid the unnecessary entry into unmatched
driver probe function for ishtp clients reported by FW.

When using this driver with the wireless dongle and some usermode
program that monitors every input device (acpid, for example), while
another usermode client opens and closes the low-level device
repeadedly, the system eventually deadlocks.
The reason is that steam_input_register_device() must not be called with
the mutex held, because the input subsystem has its own synchronization
that clashes with this one: it is possible that steam_input_open() is
called before input_register_device() returns, and since
steam_input_open() needs to lock the mutex, it deadlocks.
However we must hold the mutex when calling any function that sends
commands to the controller. If not, random commands end up falling fail.
