[media] dvb: Use DVBFE_ALGO_HW where applicable

The dvb_frontend.c core defines a FE_ALGO_HW symbol that it is
never used. Also, both cx24123 returns 1 to get_algo() callback
instead of using DVBFE_ALGO_HW.

Probably, those are some left overs from some code cleanup.

Let's stop returning magic numbers and use the proper macro
value.

[media] Technisat SkyStar USB HD,(DVB-S/S2) too much URBs for arm devices

Using 8 URBs results in a consecutive buffer allocation of too much
memory for some arm devices.
As we use isochronuous transfers the number of URBs can be reduced
without risking data-loss.

[media] rc-core: improve the lirc protocol reporting

Commit 275ddb40bcf686d210d86c6718e42425a6a0bc76 removed the lirc
"protocol" but kept backwards compatibility by always listing
the protocol as present and enabled. This patch further improves
the logic by only listing the protocol if the lirc module is loaded
(or if lirc is builtin).

Note that the 6 in the third argument of memset appears to represent

[media] x86/mm/pat, drivers/media/ivtv: move pat warn and replace WARN() with pr_warn()

On built-in kernels this warning will always splat as this is part
of the module init. Fix that by shifting the PAT requirement check
out under the code that does the "quasi-probe" for the device. This
device driver relies on an existing driver to find its own devices,
it looks for that device driver and its own found devices, then
uses driver_for_each_device() to try to see if it can probe each of
those devices as a frambuffer device with ivtvfb_init_card(). We
tuck the PAT requiremenet check then on the ivtvfb_init_card()
call making the check at least require an ivtv device present
before complaining.

[media] pci/Kconfig: don't use MEDIA_ANALOG_TV_SUPPORT for grabber cards

I noticed certain cards are currently under MEDIA_ANALOG_TV_SUPPORT
but it seems they are frame grabbers (with CVBS, Svideo etc. inputs)
rather than TV receivers (with analog TV tuners).

MEDIA_CAMERA_SUPPORT maybe isn't the best name (only "meye" driver seems
to drive a real camera in a laptop) but it at least doesn't select the
TUNERs.

Perhaps the following patch would make sense.
