ASoC: Intel: Atom: add definitions for modem/SSP0 interface
The Atom DPCM driver only allowed for the SSP2 interface, add definitions for modem/SSP0. These definitions might be used to route audio to a codec connected to SSP0 (instead of a modem in traditional usages), but there is a restriction to 2ch I2S. SSP2 is capable of handling up to 4 slot TDM. Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
