arch/x86/acpigen: refactor calls to acpigen_write_register

All of the callers to acpigen_write_register() also make calls to
acpigen_write_resourcetemplate_[header|footer](). This change introduces
acpigen_write_register_resource() to unify all of those trio of calls
into one.  I also made the input parameter const.
