Same vas_window struct is used on powerNV and pseries. So this patch
changes in struct vas_window to support both platforms and also the
corresponding modifications in powerNV vas code.
On powerNV vas_window is used for both TX and RX windows, whereas
only for TX windows on powerVM. So some elements are specific to
these platforms.
