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.

sound/soc/intel/baytrail is a niche solution which supports limited
number of BYT products - as described by
snd_soc_acpi_intel_baytrail_legacy_machines table. For a long time it's
deprecated in favor of sound/soc/intel/atom solution with SOF providing
support for some products too effectively rendering /baytrail/ redundant.
Remove deprecated code from ASoC tree.

sst-firmware is host to many image loading over DMA operations. Majority
of code targets sound/soc/intel/haswell solution as /baytrail/ never
switched to DMA-based firmware loading. With /haswell/ removed this code
serves no purpose. Address this redundancy.
