[Qemu-devel] [RFC 3/3] pseries: Advertise HPT resize capability

[David Gibson <david@gibson.dropbear.id.au>]

This adds a new string to the hypertas property in the device tree,
advertising to the guest the availability of the HPT resizing hypercalls.
This is a tentative suggested value, and would need to be standardized by
PAPR before being merged.
