spapr/ddw: Implement 64bit query extension
PAPR 2.8 (2018) defines an extension to return 64bit value for
the largest TCE block in "ibm,query-pe-dma-window". Recent Linux kernels
support this already.
This adds the extension and supports the older format.
This advertises a bigger window for the new format as the biggest
window with 2M pages below the start of the 64bit window as it is
the maximum we will see in practice.
