remoteproc: Reduce asynchronous request_firmware to auto-boot only

Browse Source 
The rproc_add_virtio_devices() requests firmware asynchronously and
triggers boot if the auto_boot flag is set. However, this
asynchronous call seems to be redundant for non auto-boot scenario
since the rproc_boot() would call request_firmware() anyways. Move
the auto_boot check to rproc_add() so that a redundant call to
_request_firmware can be avoided for non auto-boot case.
