Cleanup the ddbridge's dummy driver by removing the parts
that aren't needed by ddbridge, adding it to the building
system and changing the binding at the driver to use the
newer function name.

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

The Octopus V3 and Octopus Mini devices support set up of a dummy tuner
mode on port 0 that will deliver a continuous data stream of 125MBytes
per second while raising IRQs and filling the DMA buffers, which comes
handy for some stress, PCIe link and IRQ handling testing. The dummy
frontend is registered using dvb_dummy_fe's QAM dummy frontend. Set
ddbridge.dummy_tuner to 1 to enable this on the supported cards.
Picked up from the upstream dddvb-0.9.33 release.

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.

This enables MaxS4/S8 and Octopus Max card support in ddbridge by adding
glue code into ddbridge-core, having another PCI ID, and have the LNB IC
control code (and all other MaxS4/8 related code) in ddbridge-maxs8.c
(rather than another ~400 LoC in ddbridge-core.c like it's done in the
original vendor driver package).

It is known that MSI interrupts - while working quite well so far - can
still cause issues on some hardware platforms (causing I2C timeouts due
to unhandled interrupts). The msi variable/option is set to 1 by default.
So, add a Kconfig option prefixed with "EXPERIMENTAL" that will control
the default value of that modparam, defaulting to off for a better
user experience and (guaranteed) stable operation "per default".

This adds all required glue code to support - in conjunction with the new
stv0910 and stv6111 demod/tuner drivers and additionally the lnbh25 LNB
controller driver - all current DVB-S/S2 hardware (bridges and flex
modules) from Digital Devices like the DD CineS2 V7 and V7A, current
S2 V4 DuoFlex modules, and probably all upcoming devices based on this
STV0910/STV6111/LNBH25 hardware stack.

Properly detect and attach Ports and Flex modules with the Sony CXD28xxER
series demods. This makes newer Cine cards and most DuoFlex C/C2/T/T2 (or
any combination of these systems) work, PCI IDs need to be added though.
Note: This utilises the CXD2841ER demod driver, which requires the changes
from this patch series to properly work. Without those changes, it won't
function properly (if at all).

This adds detection and activation for STV0367-based tuner hardware (namely
CineCTv6 bridge cards and older DuoFlex CT addon modules). Utilises the
extended stv0367 demod driver.
TDA18212 i2c_client/regmap-api code was originally implemented by
Antti Palosaari <crope@iki.fi> in a variant to update the ddbridge code
from the vendor dddvb package (formal ack for these parts received).
Original patch at [1].
When boards with STV0367 are cold-started, there might be issues with the
I2C gate, causing the TDA18212 detection/probe to fail. For these demods,
a workaround (tuner_tda18212_ping) is implemented which probes the tuner
twice on this hardware constellation which will resolve the problem and
put all components into a working state. Other demod/port types won't be
retried.

Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.
That simplifies the life for users, as they can just keep
this untouched.
Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.
