ALSA: compress: fix an integer overflow check

I previously added an integer overflow check here but looking at it now,
it's still buggy.

The bug happens in snd_compr_allocate_buffer().  We multiply
".fragments" and ".fragment_size" and that doesn't overflow but then we
save it in an unsigned int so it truncates the high bits away and we
allocate a smaller than expected size.

ALSA: hda - Add NULL check to all PM ops in hda_intel.c

Since devptr can be NULL due to asynchronous probe, all PM ops should
have NULL checks at the beginning.

ALSA: pcm: Introduce protocol version field to sw_params

For controlling the new fields more strictly, add sw_params.proto
field indicating the protocol version of the user-space.  User-space
should fill the SNDRV_PCM_VERSION value it's built with, then kernel
can know whether the new fields should be evaluated or not.

And now tstamp_type field is evaluated only when the valid value is
set there.  This avoids the wrong override of tstamp_type to zero,
which is SNDRV_PCM_TSTAMP_TYPE_GETTIMEOFDAY.

ALSA: pcm: Add tstamp_type and proto to sw_params compat layer

I forgot to add the new fields in sw_params to 32bit compat layer.

ALSA: hda - Add mic fixup for Gigabyte BXBT-2807

The Gigabyte BRIX BXBT-2707 is a mini-PC with Realtek ALC283 HDA,
exposing a single headset jack.

However, the default pin config information only suggests
that one pin is connected: a HP out jack (pin 0x21, default
config 0x04211010).

The microphone input is behind pin 0x19, which has default
config 0x411111f0 (i.e. unused), so it does not show up in
userspace, and no microphone input is possible via the headset.

Override the pin config so that the headset mic can be used.
