Now that the SPDX tag is in all greybus files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/greybus files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

Currently, if info is null, the dev_err message is dereferencing an
uninitialized module pointer. Instead, it should use codec->dev pointer
in dev_err call and better align with other err msg in this function.
Also, ret variable might be used uninitialized in a specific case.
Avoid using it this way.

Added extra fields namely jack_mask & button_mask for each module_info.
These fields are required while registering jack & reporting jack
events.
Earlier, these were hard coded values assuming fixed capabilities say
HEADSET, LINEOUT, etc. supported by GB-codec driver. Now these are
computed dynamically based on module's jack capability shared via
topology data.

Earlier, module path was enabled based on module's control switch e.g.
'SPK Amp switch'. Thus widget's name was sufficient to parse and
identify the direction. Now individual modules' path will be enabled
based on AIF widget status. So, it is required to get complete widget
details, say w->type is used to identify direction (playback/capture)
and w->sname is used to identify module's DATA connection used for
communication via greybus.

There's an issue that the userspace is not able to control both the
enumerated control and DAPM widget when audio bundle is in the SUSPEND
state. This patch fixes the issue by adding pm_runtime_get/put() calls
for the both controls.
Testing Done:
- Use tinymix to get and put both enumerated control and DAPM widget as
the followings, and observe audio bundle is able to wake up from
suspend.
$ tinymix "GB 3 PB source" 1
$ tinymix "GB 3 PB source"
GB 3 PB source: AIF1 >AIF2
$ tinymix "GB 3 AIF1_RX MUX" 2

there is race condition between _disconnect() request &
stop_trigger() in case of abrupt module removal.
And sometimes this can lead to deadlock while acquiring
codec_info->lock.
To avoid such situation, atomic variable is used to maintain
codec connected state.
During dai operations (trigger, shutdown, etc.), 'is_connected'
variable is validated to avoid unnecessary lock acquire in
case module already removed.

For each GB codec module inserted, DAPM widgets, kcontrols, routes
and DAIs can be fetched through greybus in a binary chunk and parsed
locally to create & populate DAPM graph for the specific module.
It is required by each codec module to populate a minimum set of
kcontrols with fixed names to support basic audio usecase.
To support advanced features of codec module, the same can be polpulated
with existing topology parser. However, to use them for different usecase
separate mechanism (may be via MSP) is required to inform userspace about
their configuration value & enable/disable sequence.
ToDos:
Currently, support for enumerated kcontrol/dapm control is hardcoded.
Need to add complete logic within the parser.
