intel_adsp: ace: split power/boot/recovery defines from main header

Split the defines based on domain and cleanup ace_v1x-regs.h so we can
finally remove it and stop include soc specific headers across the tree.
Future generations of this family will be able to use the same naming
scheme without having to use the version name in the file name.
