pseries: Allow RTAS tokens without a qemu handler

Kernel-based RTAS calls will not have a qemu handler, but will
still be registered in qemu in order to be assigned a token
number and appear in the device-tree.

Let's test for the name being NULL rather than the handler
when deciding to skip an entry while building the device-tree
