[PATCH 5.4 167/215] virtio: virtio_console: add missing MODULE_DEVICE_TABLE() for rproc serial

From: Greg Kroah-Hartman

From: Alexander Lobakin <alobakin@xxxxx>

commit 897c44f0bae574c5fb318c759b060bebf9dd6013 upstream.

rproc_serial_id_table lacks an exposure to module devicetable, so
when remoteproc firmware requests VIRTIO_ID_RPROC_SERIAL, no uevent
is generated and no module autoloading occurs.
Add missing MODULE_DEVICE_TABLE() annotation and move the existing
one for VIRTIO_ID_CONSOLE right to the table itself.

Fixes: 1b6370463e88 ("virtio_console: Add support for remoteproc serial")
