The GPIO line used for the mute LED control on Lenovo Yxx0 laptops is
cleared unexpectedly when the codec goes to D3, typically by
power-saving.  For avoiding it, add a power filter in the fixup.

While moving the card device into struct snd_card, the reference to
the assigned card in sysfs show/store callbacks were forgotten to be
refreshed, still accessing to the no longer used drvdata.  Fix these
places to refer correctly via container_of().

Also, remove the superfluous NULL checks since it's guaranteed to be
non-NULL now.

Avoid traversing the device object list of the card instance just for
checking the PCM streams.  The driver's private object already
contains the array of substream pointers, so it can be simply looked
through.  The card internal may be restructured in future, thus better
not to rely on it.

Also, this fixes the possible deadlocks in PCM mutex.  Instead of
taking multiple PCM mutexes, just take the common mutex in all
places.  Along with it, rename prepare_mutex as pcm_mutex.

Some codec drivers still have it since using PCI_VENDOR_ID_*.

Realtek codec driver contains some codes referring to the PCI
subdevice IDs, but most of them are optional, typically for checking
the codec name variants.  Add NULL checks appropriately so that it can
work without PCI assignment.

The default parent device can be obtained directly via card object, so
we don't need to rely on pci->dev.parent.  Since there is no access to
pci_dev, we can reduce the inclusion of linux/pci.h, too.

Function del_timer() does not guarantee that timer was really deleted.
If the timer handler is beeing executed at the moment, the function
does nothing. So, it's possible to use already freed memory in the handler:

Using __bitwise and typedefs for the attributes of snd_device struct
isn't so useful, and rather it worsens the readability.  Let's drop
them and use the straightforward enum.

As prepared in the previous patch, we are ready to create a device
struct for the card object in snd_card_create() now.  This patch
changes the scheme from the old style to:

- embed a device struct for the card object into snd_card struct,
- initialize the card device in snd_card_create() (but not register),
- registration is done in snd_card_register() via device_add()

The actual card device is stored in card->card_dev.  The card->dev
pointer is kept unchanged and pointing to the parent device as before
for compatibility reason.
