Building the samples/subsys/ipc/openamp_rsc_table/ sample generates the
following warning:

[24/182] Building C object zephyr/CMakeFiles/zephyr.dir/lib/open-amp/resource_table.c.obj
In file included from /zephyrproject/zephyr/lib/open-amp/./resource_table.h:11,
                 from /zephyrproject/zephyr/lib/open-amp/resource_table.c:30:
/zephyrproject/modules/lib/open-amp/open-amp/lib/include/openamp/virtio.h:83:2:
 warning: #warning "VIRTIO_DRIVER_SUPPORT and/or VIRTIO_DEVICE_SUPPORT should be defined" [-Wcpp]
   83 | #warning "VIRTIO_DRIVER_SUPPORT and/or VIRTIO_DEVICE_SUPPORT should be defined"
      |  ^~~~~~~

The issue occurs because the project includes the virtio API while
VIRTIO_DRIVER_SUPPORT and VIRTIO_DEVICE_SUPPORT is only defined for
the open-amp library build.

Fix the warning by testing deprecated usage of VIRTIO_DRIVER_ONLY and
VIRTIO_DEVICE_ONLY but not under
#if !defined(VIRTIO_DRIVER_SUPPORT) && !defined(VIRTIO_DEVICE_SUPPORT)
condition.

…RIVER

The virtio.h header can be included by applications. In such cases,
VIRTIO_DRIVER_SUPPORT and VIRTIO_DEVICE_SUPPORT, which are used to
optimize the library, may not be defined in the application.

Define default VIRTIO_ROLE_IS_DEVICE and VIRTIO_ROLE_IS_DRIVER macros
that do not check for VIRTIO_DEVICE_SUPPORT or VIRTIO_DRIVER_SUPPORT if
they are not defined.

This patch fixes the rpmsg_create_ept function passing the endpoint's private
data that can be set by the application before the call of
rpmsg_create_ept.
