The host calls this function to bind a PE to an XIVE. Only that PE may then signal an MSI that selects this XIVE.

is the index of a PE, from 0 to ibm,opal-num-pes minus 1.
is the index, from 0 to ibm,opal,ibm-num-msis minus (num_lsis+1)
This call maps the XIVR indexed by xive_num to the PE specified by pe_number. For ibm,opal-ioda HW, the pe_number must match the pe_number set in the MVE.
