arc: kgdb: add default implementation for kgdb_roundup_cpus()
arc supports kgdb, but need update -- add function kgdb_roundup_cpus(),
or can not pass compiling. At present, add the simple generic one just
like other architectures(e.g. tile, mips ...).
The related error (with allmodconfig):
kernel/built-in.o: In function `kgdb_cpu_enter':
kernel/debug/debug_core.c:580: undefined reference to `kgdb_roundup_cpus'
