spapr: Enable dynamic change of the supported hypercalls list
At the moment the "ibm,hypertas-functions" list is fixed. However some
calls should be listed there if they are supported by QEMU or the host
kernel.
This enables hyperrtas_prop to grow on stack by adding
a SPAPR_HYPERRTAS_ADD macro. "qemu,hypertas-functions" is converted as well.
The first user of this is going to be a "multi-tce" property.
