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.

The DVB part of the media API documentation has several
legacy things on it:
	- Examples that don't work;
	- APIs unused and deprecated;
	- places mentioning the wrong API version.

reflect the cleanup efforts to make it more consistent with
the current status of the API.

The notes there are somewhat confusing and assumes that the
reader would have read the DVBv3 way. This is not true anymore,
as the DVBv3 is now on a separate section that is marked as
deprecated.

The fe_type is deprecated at the DVB API. However, it may still

used, instead, in order for legacy apps to support newer hardware.

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
a separate patch.

Move the function ioctl definitions to the end of the chapter,
at their importance. That makes the document better organized,
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.

This one is not documented, nor it should, as this is
there just to reserve namespace:

But those are already documented together with other ioctls:

	Warning: can't find reference for VIDIOC_UNSUBSCRIBE_EVENT ioctl
	Warning: can't find reference for FE_GET_PROPERTY ioctl
	Warning: can't find reference for VIDIOC_SUBDEV_G_EDID ioctl
