HID: intel-ish-hid: Constify lowlevel HID driver

Since commit 52d225346904 ("HID: Make lowlevel driver structs const")
the lowlevel HID drivers are only exposed as const.

Take advantage of this to constify the underlying structure, too.

Only include intel-ish-client-if.h, which has all interfaces required to
implment ISHTP client. There is no longer any direct field access from
core ISHTP only include files.

HID: intel-ish-hid: Hide members of struct ishtp_cl_device

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.

HID: intel-ish: enable raw interface to HID devices on ISH

Raw interface is often used to update firmwares in HID devices.
We are enabling the interface to support in-field firmware update
for the HID devices attached to ISH.

HID: intel-ish-hid: Use VID/PID from ISH

The Intel ISH HID can now have other devices attached to it, not just
sensors. Hence ISH HID transport is no longer just used for sensors.
Currently the vendor and product id is hardcoded for sensors, but they
can be obtained from ISH firmware for the real device. The driver already
extract them and store as part of device_info structure in client_data.
So use vendor id/product id obtained from the ISH firmware.

HID: intel-ish-hid: ISH HID client driver

This driver is responsible for implementing ISH HID client, which
gets HID description and report. Once it has completely gets
report descriptors, it registers as a HID LL drivers. This implements
necessary callbacks so that it can be used by HID sensor hub driver.
