#     powerpc/papr_scm: Use the correct bind address
#     
#     When binding an SCM volume to a physical address the hypervisor has the
#     option to return early with a continue token with the expectation that
#     the guest will resume the bind operation until it completes. A quirk of
#     this interface is that the bind address will only be returned by the
#     first bind h-call and the subsequent calls will return
#     0xFFFF_FFFF_FFFF_FFFF for the bind address.
#     
#     We currently do not save the address returned by the first h-call. As a
#     result we will use the junk address as the base of the bound region if
#     the hypervisor decides to split the bind across multiple h-calls. This
#     bug was found when testing with very large SCM volumes where the bind
#     process would take more time than they hypervisor's internal h-call time
#     limit would allow. This patch fixes the issue by saving the bind address
#     from the first call.
