This commit removes the dependency of the fakesensor API on
`SENSORS_GNSS`. All of the logic for handling fake GNSS sensors is
conditionally compiled only if GNSS features are enabled. Other fake
sensors can be used without GNSS logic being included in the build.

Calling `virtio_free_buf` or `kmm_free` inside IRQ may lead to dead lock
inside `mm_free`, so we use a free list to store the buffer and reuse it
next time. Fortunately, NuttX only uses one async buffer at same time,
so we don't need to consider how to free the buffer because we won't
have too many in the free list.

The rpmsg_ioctl() function will first obtain the read lock before
traversing g_rpmsg, then the rpmsg_dev_destory function will try
to obtain the write lock.
At this time, rpmsg_ioctl does not release the read lock, resulting
in a deadlock.
To solve this problem, add a standardalone list for the rptun instance
to avoid hold the rpmsg lock when execute rptun_poweroff()

When execute 'rptun stop /dev/rptun/proxy' in the nsh,
rpmsg_deinit_vdev(&priv->rvdev) will set rvdev->vdev = NULL,
then the remoteproc_remove_virtio(priv->rvdev.vdev) input is NULL,
which will cause crash, the backtrace as follow, so we save the
rvdev->vdev pointer on vdev to solve this problem.

The reference count (upper->crefs) is incremented in timer_open()
only after ensuring it will not overflow, timer_close() is only
called after a successful open. Therefore, crefs should never be
zero when timer_close() is called. The check for crefs > 0 before
decrementing is unnecessary and has been removed to simplify the code.

The reconnect will fail because the state changes to connecting when

Introduce a single configuration option to provide strict transmit
priority ordering based on CAN ID.
The intention is to expose the user-visible behavior (strict TX
priority ordering) rather than the underlying implementation details.
Strict priority ordering is only meaningful when hardware transmit
buffer cancellation is available, so splitting this functionality into
separate configuration options was misleading and could result in
partially effective or incorrect configurations.
