Got ride of a variable that counted the number of devices in

It was a struct cx8802_driver for no apparent reason. Nothing uses a
cx8802_driver in the cx8802_dev struct. The only field that was used was
devlist, a list_head.
The code in cx8802_remove() that removed any loaded sub-drivers was broken.
It would delete the current list entry, but didn't use list_for_each_safe. It
also called list_del() on the list _head_ inside the list_for_each loop? It
would crash if it was run, which I don't think can ever happen.
Since the cx8802 sub-drivers use the cx8802 driver, they have to be unloaded
first. So there isn't any way for a sub-driver to still be loaded when
cx8802_remove() is called... Except maybe with PCI hot-plug, if one removes
the PCI card while the drivers are loaded?
So I left some code in to handle that if it's actually possible. It will
remove the sub-drivers from the device cx8802_remove() was called on, and only
that device. If one has two DVB cards and unplugs one, there is no reason to
unload the DVB drivers for both cards. I have no way to test this, but it
can't be worse than what was there before.
cx8802_get_driver() is passed a cx8802_dev pointer and looks for the requested
driver on that device. It first loops over the cx8802 device list looking for
the device it was passed, which is pointless. It doesn't need to find the
device pointer in the list, as it already has the pointer.
The list_head in the cx8802_driver struct, which joins all the _drivers_
attached to a device, was named devlist. Changed that to drvlist, since the
devlist is used for a list of _devices_ in other cx8802 structs.

card_priv was only used to store a pointer to the vp3054 state struct.
There's no need to use a void * since it doesn't have multiple types.
Make the field conditional on VP3045 support. It was already conditional on
DVB support, but it's only used if VP3045 support is on, so that makes for a
better option to check.

Fixes few more problems I found in my saa7134 resume code:
* Race between IRQ handler and .suspend()/.resume() functions
* Removes timeout timers on active buffers - those
buffers will be recaptured after resume
* Adds suspend/resume for IR code - probably
necessary if using polling mode
* Adds #ifdef CONFIG_PM overs suspend code
* Runs a quirk in set_tvnorm in suspend/resume too
* Rearranges the order of calls in saa7134_resume to
be exactly as in saa7134_initdev thus the card is
initialized in exactly the same way
* Since DMA audio capture suspend/resume isn't yet supported,
avoid re-enabling it on resume for now

Both cx23885_initdev and cx23885_dev_setup free the device in their
error path so a failure in the latter causes a double-free. Since
cx23885_dev_setup is only called from cx23885_initdev, it should be safe
to remove its deallocation and leave the cleanup up to the allocating
function.

Add two mute controls. One mutes everything, the other just mutes the analog
pass-through output.
Rename the existing volume control. The controls are now:
Playback Volume
Playback Switch
Capture Switch
These names might seem odd, but I believe they are more correct. The previous
"Capture Volume" control didn't actually effect the volume of the captured
audio. Instead it controls the volume of the analog pass-thought output. It
appears that pass-through controls like this are usually considered to be in
the playback direction, not capture. For example, "CAPTURE feedback Playback
Volume" is the name used for a control that appears to have the same effect in
the ca0106 driver. We only have one volume control, so we can omit the
"CAPTURE feedback" part.
If someone where to add PCM playback support to the driver, then this would be
the volume control.
