pseries: Enable HPT resizing for 2.10
We've now implemented a PAPR extensions which allows PAPR guests (i.e. "pseries" machine type) to resize their hash page table during runtime. However, that extension is only enabled if explicitly chosen on the command line. This patch enables it by default for spapr-2.10, but leaves it disabled (by default) for older machine types.
