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

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.

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.

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.
