When monitoring multiple capture channels, the `ioctl` function
is called three times, leading to significant overhead mainly due
to VFS and `nxmutex_lock/unlock`. Adding a new interface can save
the overhead of two `ioctl` calls.

reason:
Only one timer will be effective at a time.In the current
implementation of NuttX's timer handling, only a single global timer is necessary.
Having an excessive number of timers can lead to additional performance
overhead and logical errors, especially when operating in SMP
(Symmetric Multi-Processing) tickless mode.

When the system cannot obtain buffers for a long time, hpwork will hold
a lot of buffers. However, due to a deadlock between the rptun thread
and hpwork, hpwork cannot send the buffers in time, causing the system
to crash.
so, avoid hold sre lock in rptun thread.

if remote not set CONFIG_SENSOR_RPMSG, local can't receive NS_ACK
so sensor_rpmsg_device_ns_bound won't be called, not add sre->node
when local stop remote, rpmsg_deinit_vdev will call sensor_rpmsg_ns_unbind_cb
if (ept && ept->ns_unbind_cb)
ept->ns_unbind_cb(ept);
list_delete node is NULL at sensor_rpmsg_ns_unbind_cb

When the ipc buffer is obtained for the first time due to insufficient space,
it waits due to insufficient ipc buffer.
At this time, if rptun recursively operates the next ipc request, the ipc buffer
will be reused, but it has been released at this time.

by doing this we can reduce context switch time,
