powerpc/32s: Slenderize _tlbia() for powerpc 603/603e
_tlbia() is a function used only on 603/603e core, ie on CPUs which
don't have a hash table.
_tlbia() uses the tlbia macro which implements a loop of 1024 tlbie.
On the 603/603e core, flushing the entire TLB requires no more than
32 tlbie.
Replace tlbia by a loop of 32 tlbie.
