Add missing functions to query the single fixed frame size (960x540) and
supported frame rates. Technically, the SUR40 supports any arbitrary frame
rate up to 60 FPS, as it is polled and not interrupt-driven. For now, we
just report 30 and 60 FPS, which is sufficient to make most V4L2 tools work.

The SUR40 hardware can deliver images at up to 60 FPS; at full USB2 bandwidth,
one raw frame will take about 11 ms to transmit. If the poll interval is above
5 ms, fully handling one frame will take longer than 16 ms and the overall
frame rate will drop below 60 FPS. To get the full frame rate without blocking
all the time and still allowing for a bit of timing jitter, we reduce the poll
interval to 4 ms.

The log_status ioctl should report if the audio input has mode Bilingual. However, the
check against the itv->dualwatch_stereo_mode is completely wrong and is a left-over from
the distant past. Not only is the bitmask obviously wrong, the test itself is broken too
since itv->dualwatch_stereo_mode is no longer a bitmask at all.

The interrupt bit assignments use for the adv7511 were off by one.
This means that the current scheme (bit << (4 * stream_index)) can
no longer be used.
Fix this by precalculating and storing the correct masks in the
cobalt_stream struct.
This wasn't noticed before because the adv7511 interrupts are very
rare. But for CEC support these interrupts are essential, so this made
me realize that it wasn't working correctly.

What's written there about the arguments for this ioctl
is bogus: it doesn't return an enum (or a typedef)
for enum fe_status. Instead, it returns a bitmask with the
values defined by enum fe_status.
Also, the size of the integer returned is not 16 bits, but,
instead, sizeof(fe_status_t), e. g. sizeof(enum), with is
arch-dependent.
This should of course be fixed, but this should be done on

as the DVB frontend system call index will look like:
open()
close()
ioctl FE_GET_INFO — Query DVB frontend capabilities and returns information about the front-end. This call only requires read-only access to the device
ioctl FE_READ_STATUS — Returns status information about the front-end. This call only requires read-only access to the device
ioctl FE_SET_PROPERTY, FE_GET_PROPERTY — FE_SET_PROPERTY sets one or more frontend properties. FE_GET_PROPERTY returns one or more frontend properties.
ioctl FE_DISEQC_RESET_OVERLOAD — Restores the power to the antenna subsystem, if it was powered off due to power overload.
ioctl FE_DISEQC_SEND_MASTER_CMD — Sends a DiSEqC command
ioctl FE_DISEQC_RECV_SLAVE_REPLY — Receives reply from a DiSEqC 2.0 command
ioctl FE_DISEQC_SEND_BURST — Sends a 22KHz tone burst for 2x1 mini DiSEqC satellite selection.
ioctl FE_SET_TONE — Sets/resets the generation of the continuous 22kHz tone.
ioctl FE_SET_VOLTAGE — Allow setting the DC level sent to the antenna subsystem.
ioctl FE_ENABLE_HIGH_LNB_VOLTAGE — Select output DC level between normal LNBf voltages or higher LNBf voltages.
ioctl FE_SET_FRONTEND_TUNE_MODE — Allow setting tuner mode flags to the frontend.
