1. * Retire the Core_A folder and use a single Core folder for all proce… …

   …ssor core headers.
   
   * Separate folders for different architecture profiles (A-profile, R-profile and M-profile)
   * Top-level compiler headers will exist in the Core folder (no separate Compiler folder is needed).
   ** The cmsis_compiler.h header will continue to figure out which compiler toolchain is being used.
   ** The compiler toolchain specific headers in the Core folder will contain code common to all architecture profiles.
   ** Compiler headers specific to each architecture profiles can reside within the new architecture profile folders.
   ** The second-level files like cmsis_gcc.h are named cmsis_gcc_a.h, cmsis_gcc_r.h and cmsis_gcc_m.h to avoid having multiple files with the same name
   *For any features that are common to more than one architecture profile, e.g, the GIC is common to A-profile and R-profile, we can include the GIC header in each architectural folder, but only one of these files contains the code to avoid duplication. The file with the same name that doesn't include the code will simply include the code from the other folder- this should hopefully be clear to developers.
   * removed deprecated core_armv8xxx.h files. The files were added because no specific ARM v8-M device was available when Arm v-M support was added.
   * removed deprecated file cmsis_armcc_a.h. This compiler support is obsolete
   Add initial support for some Cortex-A and Cortex-R devices
