target/ppc: make vhyp get_pate method take lpid and return success
In prepartion for implementing a full partition table option for
vhyp, update the get_pate method to take an lpid and return a
success/fail indicator.
The spapr implementation currently just asserts lpid is always 0
and always return success.
