powerpc/mm: Don't clear _PAGE_COHERENT when _PAGE_SAO is set
The current low level hash code on LPAR configurations clears _PAGE_COHERENT (M) when either _PAGE_GUARDED (G) or _PAGE_NO_CACHE (I) is set. This conflicts with _PAGE_SAO which has M, I and W bits sets at once (normally invalid combo) to indicate the new SAO attribute. This changes the code to allow that case.
