This introduces stub implementations of the H_RESIZE_HPT_PREPARE and
H_RESIZE_HPT_COMMIT hypercalls which we hope to add in a PAPR
extension to allow run time resizing of a guest's hash page table. It
also adds a new machine property for controlling whether this new
facility is available.
For now we only allow resizing with TCG, allowing it with KVM will require
kernel changes as well.
Finally, it 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.

spapr_machine_init() leaks an Error object when
kvmppc_check_papr_resize_hpt() fails and spapr->resize_hpt is
SPAPR_RESIZE_HPT_DISABLED, i.e. when the host doesn't support hash
page table resizing, and the user didn't ask for it. As harmless as
memory leaks can possibly be. Plug it.
