[PATCH 01/13] ASoC: Intel: Remove haswell solution

Newly added catpt solution found in sound/soc/intel/catpt is a direct replacement to sound/soc/intel/haswell. It covers all features supported by it and more - by aligning to recommended flows and requirement list based on Windows driver equivalent. No harm is done to userspace as catpt - similarly to haswell - loads no extenal topology files while sharing the exact same ADSP firmware binary.

Given the above, existing haswell code is redundant so remove it.
