There are two tuner types: those for M/N standards and those for all others.
However, M/N standards are not always 60 Hz (PAL-N/Nc are 50 Hz), so rename
the module option accordingly.

There are some restrictions:
- The 2nd DVB-S section will only work if the 1st is configured for DVB-S too.
so "options saa7134-dvb use_frontend=0,1" won't work.
- Currently it is not possible to set the higher LNB supply voltages, so
14V instead of 13V in the 2nd section.
- It is not possibe to turn off the 2nd LNB supply independently.
This comes from the problem that the 2nd section can't access the i2c interface
of the LNB supply chip.

In the case of an access error to the high latency registers of
the audio DSP, the interface needs to be cleared, otherwise a cascade
of errors occurs.
This patch is closely modeled after a proposal by Mirek Slugen

If dvb_attach fails, dev->dvb.frontend is NULL. This will produce an OOPS, as

The PixelView PlayTV card definition structure was missing initialization of
the tuner_addr and radio_addr fields. As a result it was impossible to have the
tuner initialized using parameters specified while loading the bttv.ko module.
This regression became visible after the v4l rearrangements introduced
somewhere around 2.6.15 kernel version.
The root cause for the tuner initialization failure is located in the
attach_inform function in the bttv-i2c.c file.
There at the very beginning the addr variable holding the tuner device address
is initialized with the value taken from the bttv_tvcards array.
For the PixelView PlayTV card the tuner address field (and the radio address as
well) was uninitialized, and thus equal 0. Later in that function execution of
the TUNER_SET_TYPE_ADDR tuner command is guarded with check for the tuner
address either equal ADDR_UNSET, or client->addr.
Since both are non-zero (the latter in case of the card owned by me at the
runtime is equal 0x61) the TUNER_SET_TYPE_ADDR command is not executed, and
consequently in the tuner_attach function in the tuner-core.c file call to
i2c_attach_client does not result in assigning the tuner type variable with the
requested value.
Providing initialization of the tuner_addr and radio_addr with ADDR_UNSET
values as it is already done for other tv cards defined in bttv-cards.c ensures
that the tuner initialization is done correctly, just as it used to be in the
2.6.14 kernel.

In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that
involved converting !x & y to !(x & y). The code below shows the same
pattern, and thus should perhaps be fixed in the same way.
This is not tested and clearly changes the semantics, so it is only
something to consider.
The semantic patch that makes this change is as follows:

Only attach cameras to the host interface for probing, then detach until
open. This allows platforms with several cameras on an interface,
physically supporting only one camera, to handle multiple cameras and
activate them selectively after initial probing. The first attach during
probe is needed to activate the host interface to be able to physically
communicate with cameras.

The pvrusb2 driver normally picks up the default video standard from the
eeprom on Hauppauge devices, but the OnAir HDTV and OnAir Creator are not
Hauppauge devices, and do not store this information in any eeprom.
These devices support NTSC/ATSC, so we should use NTSC by default when in
analog mode.
