KVM: PPC: Book3S: Check KVM_CREATE_SPAPR_TCE_64 parameters
Although it does not seem possible to break the host by passing bad
parameters when creating a TCE table in KVM, it is still better to get
an early clear indication of that than debugging weird effect this might
bring.
This adds some sanity checks that the page size is 4KB..16GB as this is
what the actual LoPAPR supports and that the window actually fits 64bit
space.
