lower level drivers typically register with upper layers. So fix by exporting symbols from sst_platform driver for dsp driver to register to sst platform driver Now this driver doesnt depend on sst driver, so remove the dependency and the header files Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
