remoteproc: core: Task sync during rproc_fw_boot()
By default, rproc_fw_boot() needs to wait for rproc to be configured,
but a race may occur when using rpmsg/virtio. In this case, it can
be called locally in a safe manor.
This patch represents two usecases:
- External call (via exported rproc_boot()), which waits
- Internal call can use 'nowait' version of rproc_boot()
