ASoC: cygnus: remove redundant assignment to pointer 'res'
The pointer res is being initialized with a value that is never read
and re-assigned immediately after, hence the initialization is redundant
and can be removed.

Cleans up clang warning:
sound/soc/bcm/cygnus-ssp.c:1284:19: warning: Value stored to 'res'
during its initialization is never read

Christos Gkekas 4c75968a1b ASoC: cygnus: Remove unnecessary active_slots check
Variable active_slots is unsigned so checking whether it is less than
zero is not necessary.

Lori Hikichi 934e4885cb ASoC: cygnus: Remove support for 8 bit audio and for mono
These modes of operation were not working properly and it is
unclear if the hardware could fully support these modes properly.
There is little to be gained by enabling these modes, therefore,
we will just remove support.

Lori Hikichi fcf30f3b43 ASoC: cygnus: Remove set_fmt from SPDIF dai ops
The SPDIF port cannot modify its format so a set_fmt function is not
needed. Previously, we used a generic set_fmt for all ports and returned
an error code for the SPDIF port. It is cleaner to not populate the
set_fmt field.

Lori Hikichi d8302aa6b5 ASoC: cygnus: Add EXPORT_SYMBOL for helper function
The helper function cygnus_ssp_set_custom_fsync_width() is intended
to be called from an ASoC machine driver, need to export symbol
if using modules.

Bhumika Goyal cc6e25631d ASoC: bcm: make snd_soc_dai_driver const
Make this const as it is only used during a copy operation.
Done using Coccinelle.

Simran Rai a6ee05d94e ASoC: cygnus: Add Cygnus audio DAI driver
This patch adds Cygnus audio DAI driver. It supports I2S, TDM
and SPDIF modes and uses three clocks derived from PLL.

This patchset has been tested on Cygnus wireless audio
bcm958305K board.
