KVM uses same WIM tlb attributes as the corresponding qemu pte.
For this we now search the linux pte for the requested page and
get these cache caching/coherency attributes from pte.

On booke, struct tlbe_ref contains host tlb mapping information
(pfn: for guest-pfn to pfn, flags: attribute associated with this mapping)
for a guest tlb entry. So when a guest creates a TLB entry then
struct tlbe_ref is set to point to valid pfn and set attributes in

lookup_linux_pte() is doing more than lookup, updating the pte,
