tlbia and PPC603

[Etsushi Kato]

Thank you for information, Gabriel and Ben.

I learned ppc603 software hash table some extent.  And I finally
noticed the bug in current arch/ppc/mm/ppc_mmc.c.  In old code, there
was blr at hash_page[0] and did flush_icache_range() from hash_page[0]
to hash_page[1].  But in current code, this code is removed when
comparing CPU_FT_HPTE_TABLE.

Adding this to current ppc_mmu.c have solved random crash both in
Nubus Performa and UMAX C500.  And isync before tlbie and mtsrin seems
to be not necessary.
