We need to search linux pte to get pte attributes for
setting TLB in KVM.
This patch defines a linux_pte_lookup() function for same.

kvm: powerpc: use cache attributes from linux pte
- 1st Patch fixes a bug in booke (detail in patch)
- 2nd patch is renaming the linux_pte_lookup_function() just for clarity.
There is not functional change.
- 3nd Patch adds a Linux pte
lookup_linux_pte() is doing more than lookup, updating the pte,
so for clarity it is renamed to lookup_linux_pte_and_update()

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
flags field of the above
This patch adds an helper routine kvmppc_ld_inst() to load an
instruction form the guest. This routine will be modified in
the next patch to take into account the endian order of the
guest.

Changes in v4:
- got rid of useless helper routine
They will be used to decide whether to byte-swap or not. When Little
Endian host kernels come, these routines will need to be changed
accordingly.
