soc/intel: Refactor do_global_reset() function

List of changes:
1. Rename do_global_reset() to force_global_reset()
2. Make force_global_reset() function static
3. Implement force_global_reset() into common/reset.c to avoid
dedicated SoC implementation
4. Remove redundant force_global_reset() implementation from
dedicated SoC
5. Make direct call to global_reset() from cse_lite.c
7. Drop CONFIG_HAVE_CF9_RESET_PREPARE Kconfig from APL SoC due
to common reset (soc/intel/common/reset.c) code migration
8. Remove unused function send_global_reset() from SKL me.c due
to common reset code migration
9. Delete heci.c from APL SoC as unused
