Virtio RNG support (CONFIG_DRIVERS_VIRTIO_RNG=y) selects
CONFIG_ARCH_HAVE_RNG. On the other hand, if CONFIG_DEV_URANDOM=y,
it defaults to CONFIG_DEV_URANDOM_ARCH if CONFIG_ARCH_HAVE_RNG=y.
DEV_URANDOM_ARCH definition states that the implementation of the
/dev/urandom should be provided by the architecture-specifig logic,
including the function devurandom_register(). In this case, the
/dev/urandom may refer to the same driver as /dev/random that is
provided by the Virtio RNG driver, which is implemented by this
commit.
/dev/zero is a very commonly used config, for example use
/dev/zero to test the filesystem, mtd or block devices performance.
So let's default enable it when not enable DEFAULT_SMALL

Because rpmsg_virtio_lite is a better name to inform user that the
rpmsg virtio (original name) is a lite implementation of rpmsg virtio.

When `CONFIG_NETDEV_RSS` is disabled, `NETDEV_THREAD_COUNT` will be 1,
and we should not access `upper->sem[cpu]` with `cpu > 0`.

The fake audio driver aims to easily simulate the functions of audio driver through reading and writing files.
With it, you can conveniently customize and define various capture or playback audio drivers for debugging or automated testing.
