The open codes with the bit shift in xen_snd_front_alsa.c give sparse
warnings as the PCM format type is with __bitwise.
There is already a standard macro to get the format bits, so let's use
it instead.
This fixes sparse warnings like:

The PCM format type is with __bitwise, and it can't be converted from
integer implicitly. Instead of an ugly cast, declare the function
argument of snd_sb_csp_autoload() with the proper snd_pcm_format_t
type.

The PCM format type in snd_pcm_format_t can't be treated as integer
implicitly since it's with __bitwise. We have already a helper
function to get the bit index of the given type, and use it in each
place instead.

The PCM format type is defined with __bitwise, hence it can't be

of the messy cast flood, define the format argument of
snd_hdac_calc_stream_format() to be the proper snd_pcm_format_t type.

The virmidi output trigger tries to parse the all available bytes and
process sequencer events as much as possible. In a normal situation,
this is supposed to be relatively short, but a program may give a huge
buffer and it'll take a long time in a single spin lock, which may
eventually lead to a soft lockup.
This patch simply adds a workaround, a cond_resched() call in the loop
if applicable. A better solution would be to move the event processor
into a work, but let's put a duct-tape quickly at first.

As sparse warns, the PCM format type can't be dealt as integer as
found in Intel SST driver codes.
Fix them in the following two ways:
- The open code with snd_mask_set() and params->masks reference is
replaced with params_set_format()
- The rest codes with snd_mask_set(fmt, SNDRV_PCM_FORMAT_XXX) are
replaced with the new helper, snd_mask_set_format().

The meddlesome gcc warns about the possible shortname string in

strcat(card->shortname, card->driver);
It happens since gcc calculates the possible string size from
card->driver, but this can't be true since we did set the string just
before that, and they are much shorter.
For shutting it up, use the exactly same string set to card->driver
for strcat() to card->shortname, too.
