[PATCH 1/8] ASoC: SOF: Intel: HDA: fix core status verification

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

From: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>

When checking for enabled cores it isn't enough to check that
some of the requested cores are running, we have to check that
all of them are.
