powerpc/pseries: Add hypercall wrappers for hash page table resizing
This adds the hypercall numbers and wrapper functions for the hash page
table resizing hypercalls.
These hypercall numbers are defined in the PAPR ACR "HPT resizing
option".
It also adds a new firmware feature flag to track the presence of the
HPT resizing calls.
