similar to: [PATCH] virtio: console: Disable multiport support

Unfortunately there proved to be at least one bug which requires an ABI change, so we're best off not introducing multiport support until 2.6.35. While I generally left the multiport code paths intact, I really wanted to remove the ABI defines from the header, which meant some quite deep cuts.

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> Add a virtio remoteproc serial driver: VIRTIO_ID_RPROC_SERIAL (0xB) for communicating with a remote processor in an asymmetric multi-processing configuration. The virtio remoteproc serial driver reuses the existing virtio_console implementation, and adds support for DMA allocation of data buffers but disables support for tty

struct ports_device includes a config field including the whole virtio_console_config, but only max_nr_ports in there is ever updated or used. The rest is unused and in fact does not even mirror the device config. Drop everything except max_nr_ports, saving some memory. Signed-off-by: Michael S.

This patch modifies virtio-console to use virtio_config_val() instead of a 'if(virtio_has_feature()) vdev->config->get()' construct to retrieve optional values from the config space.

If we're using multiport, there's no point in always creating a console port. Create the console port only if the host doesn't support multiport.

The virtio-console device has recently been updated to support multiple devices and multiple ports. These ports can also function as generic serial ports. Reflect these changes in the spec.
