Currently the PCM resources are allocated only once and ever in prepare
callback, assuming that the PCM parameters are never changed.  But it's
not true.

This patch adds the call of atc->pcm_release_resources() at hw_params
and hw_free callbacks to assure that the PCM setup is done correctly
for each h/w parameter changes.

emu20k1 has a native timer interrupt based on the audio clock, which
is more accurate than the system timer (from the synchronization POV).
This patch adds the code to handle this with multiple streams.

The system timer is still used on emu20k2, and can be used also for
emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c.

In case the initalization of an soc_device failed, there is no codec
associated with it. soc_suspend() will still dereference the pointer
and cause an Ooops when entering the sleep mode.

This happens on our board with a multi-target kernel image when booted
on a machine without audio circuits.

This patch makes the code bail out very early in this special case.

Enable all three capture channels, including the missing nid 7 which is
the only one capable of capturing DMIC input

Enable Headphone amp for the HP jack. This causes a volume boost for
headphones, but does not cause any noticeable effect for light loads
like other amps, so there is no need to make it configurable.

Add Input Mix capture mux setting to capture the output of the playback
input mux (that is, what goes out the speakers except for PCM)

Hack another coef register because the stereo DMIC for some reason
produces a nonstandard sum/difference signal. I found a bit to make it
just use the sum signal for both channels, which makes it behave like a
standard mono microphone. The stereo is useless anyway (they're 1cm apart).

Tested working: Three capture channels, mic in, line in, DMIC.

Tested not working: CD. Not sure why, might be unconnected in the actual
hardware or a CD drive issue.

Also looked at SPDIF. It appears to work (emitter lights up inside the
HP out jack) but I lack a proper miniTOSLINK cable to test it.

The introduction of snd_card_set_id() added a lock on the card list
to the old choose_default_id() function when using it to implement
the new API call. This lock is needed to allow us to walk the list
and check to see if our new name is a duplicate. Unfortunately this
causes a lockup when called from snd_card_register() (in cases
where no ID is supplied for the card) since the card list is already
locked there.

Fix this fairly hideously by factoring out the implementation and
using a flag to indicate if the lock should be held. A better fix
would probably be to refactor snd_card_register() to move the
_set_id() outside the locking region but I can't immediately see
anything I can convince myself is safe.
