Add a tsspeed config option to struct stv0910_cfg which can be used by
users of the driver to set the (parallel) TS speed (higher speeds enable
support for higher bitrate transponders). If tsspeed isn't set in the
config, it'll default to a sane value.
This commit also updates the two consumers of the stv0910 driver (ngene
and ddbridge) to have a default tsspeed in their stv0910_cfg templates.

There are two places pointing to an unexisting "m.chehab@kernel.org"
email. I never had such email, so, I'm unsure how it ends there.
Anyway, it is plain wrong.
While here, use my canonical e-mail on a bunch of places that

all places will be pointing to the same SMTP server.

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.

Show the UCB error counts via DVBv5.
Please notice that there's no scale indication at the driver.
As we don't have the datasheet, let's assume that it is receiving
data at a rate of 10.000 packets per second. Ideally, this should
be read or estimated.
In order to avoid flooding I2C bus with data, the maximum
polling rate for those stats was set to 1 second.
