remoteproc: make rproc_boot wait for firmware_loading_completev4.6-rc3-fdma-v4-with-asoc
rproc_alloc() kicks off an asynchronous requerst_firmware_notwait.
Most rproc drivers then call rproc_boot(), although there is no
guarentee that rproc_fw_config_virtio() callback will have finished
executing by this point.
