Arrange so that the pvrusb2 driver can optionally work without a
Hauppauge ROM being present - which is fairly important for devices
that happen to not come from Hauppauge. The expected existence of a
Hauppauge ROM is now a device attribute. The tuner type is now also a
device attribute, which is consulted if there is no ROM.

Implement additional pvrusb2 device info table entries for a device
identifier and a device description. Export this information via the
driver's internal API. Make this information available via the sysfs
driver interface. Also propagate this information into the v4l2
capability structure. An app can now retrieve and report a
descriptive string about the particular type of hardware device it is
operating.

Device-specific driver behavior is now defined by generic device
characteristics rather than by specific device model information.
With this change, the hardware type field can go away, thus this
change.

The pvrusb2 driver currently supports two variants of the Hauppauge
PVR USB2. However there are other hardware types potentially
supportable, but the driver at the moment is not structured to make it
easy to describe these minor variations. This changeset is the first
set of changes to make such additional device support possible.
Device attributes are held in several tables all contained within
pvrusb2-devattr.c; all other device-specific driver behavior now
derives from these tables.

This is a new implementation for video pipeline control within the
pvrusb2 driver. Actual start/stop of the pipeline is moved to the
driver's kernel thread. Pipeline stages are controlled autonomously
based on surrounding pipeline or application control state. Kernel
thread management is also cleaned up and moved into the internal
control structure of the driver, solving a set up / tear down race
along the way. Better failure recovery is implemented with this new
control strategy. Also with this change comes better control of the
cx23416 encoder, building on additional information learned about the
peculiarities of controlling this part (this information was the
original trigger for this rework). With this change, overall encoder
stability should be considerably improved. Yes, this is a large
change for this driver, but due to the nature of the feature being
worked on, the changes are fairly pervasive and would be difficult to
break into smaller pieces with any semblence of step-wise stability.

A previous patch implemented support for non-OFDM digital TV. However, the

s-code tables are related to IF frequency used for video demodulation.
The s-codes for analog are automatically loaded, according with video standard.
However, for digital, they will depend on the IF of the demoduler chip. IF of
the demoduler.
Before this patch, only a few IF's where possible to use. This patch allows
selecting any IF defined at firmware file.

Since check_firmware is called via analog or digital set freq routines, move
type selection to those routines. This avoids having several if's at the code,
and simplifies the source code.
A sideback effect is that implementing radio and other dvb types will become
simpler.

Note:
* At High Symbol Rates we do not have enouph machine cycles to handle the
incoming symbols and hence might run into problems at the very end of the
specified definition
* Most of the equations have been calculated for a master clock of 99 MHz,
running at 90MHz, raises lot of issues such as the need to recalculate
all of them , which is eventually very painful.
