pseries: Allow HPT resizing with KVM
So far, qemu implements the PAPR Hash Page Table (HPT) resizing extension with TCG. The same implementation will work with KVM PR, but we don't currently allow that. For KVM HV we can only implement resizing with the assistance of the host kernel, which needs a new capability and ioctl()s. This patch adds support for testing the new KVM capability and implementing the resize in terms of KVM facilities when necessary. If we're running on a kernel which doesn't have the new capability flag at all, we fall back to testing for PR vs. HV KVM using the same hack that we already use in a number of places for older kernels.
