MIPS: Use generic GCC library routines from lib/

The commit b35cd98 ("lib: Add shared copies of some GCC library routines") makes it possible to share generic GCC library routines by several architectures. This commit removes several generic GCC library routines from arch/mips/lib/ in favour of similar routines from lib/.
