After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
commit 03c835f498 ("i2c: Switch .probe() to not take an id parameter")
convert back to (the new) .probe() to be able to eventually drop
.probe_new() from struct i2c_driver.

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Static structure en_templ, of type dvb_ca_en50221, is not used except to
be copied into a local variable. Hence make it const to prevent
unintended modification of the original fields.

As both the MODULE_LICENSE and the boilerplates are now in sync and clear
that the driver is licensed under the terms of the GPLv2-only, add a
matching SPDX license identifier tag.

In commit 3db30defab4b ("use correct MODULE_LINCESE for GPL v2 only
according to notice in header") in the upstream repository for the
mentioned driver at https://github.com/DigitalDevices/dddvb.git, the
MODULE_LICENSE was fixed to "GPL v2" and is now in sync with the GPL
copyright boilerplate. Apply this change to the kernel tree driver
as well.

Three really tiny minors in this single commit which all on their own
would just clutter up the commit history unnecessarily:
* ddbridge-regs.h is lacking an include guard. Add it.
* Fix an unnecessary NULL initialisation in ddbridge-ci. The declaration
of the ci struct ptr is immediately followed by kzalloc().
* Clarify that the CXD2099AR is a Sony device in the cxd2099 driver at a
few places including Kconfig.

According to the TODO file, this driver only landed in staging because of
the way device nodes and data transfers are handled. Besides that this way
(use of secX devices) has become sort of standard to date (ie. VDR
supports this literally since ages via the ddci plugin, TVHeadend received
this functionality lately, and minisatip being currently worked on
regarding this), most importantly this I2C client only driver isn't even
responsible for setting up device nodes, not for handling data
transfer and so on, but only serves as interface for the dvb_ca_en50221
subsystem, just like every other DVB card out in the wild, with hard-wired
or such flexible CA interfaces. And, it would even work with cards having
the cxd2099 controller hard-wired.
Also, this driver received quite some love and even is a proper I2C client
driver by now. So, as this driver acts as a EN50221 frontend device, move
it to dvb-frontends. There is no need to keep it buried in staging.
This commit also updates all affected Kconfig and Makefile's, and adds
MEDIA_AUTOSELECT depends to ddbridge and ngene.
