[media] dvb-core: allow demods to specify the supported delsys

The dvb were originally written for DVB-T/C/S and ATSC. So,
the original frontend struct has fields to describe only those three
standards.

While 2nd gen standards are similar to these, new standards
like DSS, ISDB and CTTB don't fit on any of the above types.

While there's a way for the drivers to explicitly change whatever
default DELSYS were filled inside the core, still a fake value is
needed there, and a "compat" code to allow DVBv3 applications to
work with those delivery systems is needed. This is good for a
short term solution, while applications aren't using DVBv5 directly.

However, at long term, this is bad, as the compat code runs even
if the application is using DVBv5. Also, the compat code is not
perfect, and only works when the frontend is capable of auto-detecting
the parameters that aren't visible by the faked delivery systems.

So, let the frontend fill the supported delivery systems at the
device properties directly.

The future plan is that the drivers will stop filling ops->info.type,
filling, instead, ops->delsys. This will allow multi-frontend
devices like drx-k to use just one frontend structure for all supported
delivery systems.

Of course, the core will keep using it, in order to keep allowing
DVBv3 calls.

Also, set_params internally calls calc_regs().

call calc_regs() anymore. The code duplication is very small,
as most of the code there is just to check for invalid parameters.

With regards to calc_regs(), it should still trust on bandwidth and
frequency parameters passed via DVBv3, until a later patch fixes
it.

This was happening because, in the previous coding, the bandwidth

The previous patch changed the logic to estimate the bandwidth to

So, with a one-statement change, it is possible to make the tuner to

likely fix issues on countries that use 7MHz/8MHz DVB-T channels.

bandwidth. So, let's not touch on it for now.

[media] videobuf2-core: fix a warning at vb2

It seems that a cut-and-past error were added by the last patch:

drivers/media/video/videobuf2-core.c: In function ‘vb2_qbuf’:
drivers/media/video/videobuf2-core.c:1099:14: warning: comparison between ‘enum v4l2_buf_type’ and ‘enum v4l2_memory’ [-Wenum-compare]

On all places V4L2_MEMORY_USERPTR is used, it is associated with
q->memory, and not b->type. So, the fix seems obvious.

takes again driver's lock. get_userptr methods are now called with
all needed locks already taken to avoid further lock magic inside
