ALSA: compress: Add output rate and output format support

Add 'pcm_format' for struct snd_codec, add 'pcm_formats' for
struct snd_codec_desc, these are used for accelerator usage.

Current accelerator example is sample rate converter (SRC).
Define struct snd_codec_desc_src for descript minmum and maxmum
sample rates. And add 'src_d' in union snd_codec_options
structure. These are mainly used for capbility query.

ALSA: compress: add flac decoder params

The current design of sending codec parameters assumes that decoders
will have parsers so they can parse the encoded stream for parameters
and configure the decoder.

But this assumption may not be universally true and we know some DSPs
which do not contain the parsers so additional parameters are required
to be passed.

So add these parameters starting with FLAC decoder. The size of
snd_codec_options is still 120 bytes after this change (due to this
being a union)

License cleanup: add SPDX license identifier to uapi header files with a license

Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be. This makes it hard for
compliance tools to determine the correct license.

Update these files with an SPDX license identifier. The identifier was
chosen based on the license information in the file.

GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:

NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".

This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.

Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier. The format
is:
((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)

SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text. The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

ALSA: compress: Add SND_AUDIOCODEC_BESPOKE

When working with the compressed framework occasionally vendors will
use esoteric internal audio formats. For such formats it doesn't really
make sense to add an new define to the kernel as their use is not
sufficiently general.

This patch adds a new define SND_AUDIOCODEC_BESPOKE that vendors can use
in such situations.
