Supports the flush operation of the sensor.
The application can initiate a flush action through ioctl SNIOC_FLUSH
to trigger flush, and the call will be returned immediately.
Using SNIOC_GET_EVENTS to clear flush event,
However, the flush implementation is asynchronous, when all the flush
data is push to upper circbuffer, the POLLPRI event(FLUSH_COMPLETED)
will be reported.

When there is an actual physical sensor, the driver must implement the get info interface. The upper layer can obtain the actual physical sensor information through SNIOC_GET_INFO.
SNIOC_SET_INFO can only set the information of the local virtual sensor, which means it is bound to the local advertisement. Remote subscribers cannot set the information.
Usage:
struct sensor_device_info dev_info;
orb_ioctl(fd, SNIOC_GET_INFO, (unsigned long)(uintptr_t)&dev_info);
or:
ret = orb_set_info(fd, &dev_info);
ret = orb_get_info(fd, &dev_info);

The interaction between the shell service in adb and adbd occurs through a pseudo-terminal (pty).
so, when a command is launched through adb shell from a PC, users now have the ability to pause
or kill the launched,application by inputting specific commands CONFIG_TTY_SIGTSTP_CHAR or
CONFIG_TTY_SIGTINT_CHAR, akin to the capabilities provided by nsh.

Add get_local_cpuname to the rpmsg framework ops to support communicate
with the same remote core with multi rpmsg transport.
Some rpmsg services will send local cpu name to remote core and then let
remote core to connect local core by using this cpu name, when there are
multi rpmsg channels with same remote core, the remote core may connect
to incorrect core, so use the error rpmsg channel.
For example, there are two rpmsg channels between ap and audio:
ap core audio core
[ap1] <-- rpmsg virtio1 --> [audio1]
[ap2] <-- rpmsg virtio2 --> [audio2]
When we want to use the rpmsg virtio1 to communicate, ap core may send
local cpuname "ap2" to audio, so the audio core use remote cpu "ap2" to
connect with ap, and resulting in the use of incorrect rpmsg channel.

Rpmsg Router is new rpmsg transport layer, it can router the rpmsg
messages to a cpu that not directly connected with local cpu by Rpmsg,
For the rpmsg services, it is as if there is a real Rpmsg Channel between
the local cpu and the remote cpu.
For examples, there are three cpus: ap, cp and audio.
ap and cp, ap and audio has share memory and be connected by Rpmsg VirtIO,
so ap and cp, ap and audio can communicate with each other by Rpmsg, but
cp can not communicate with audio direclty.
[cp] <-- rpmsg virtio --> [ap] <-- rpmsg virtio --> [audio]
With rpmsg router, the cp can communicate with audip by Rpmsg dereclty because
the router in ap will forward the rpmsg message from cp/audio to audio/cp, like
this:
+<----- rpmsg router --> hub <-- rpmsg router ------>+
| | |
[cp] <-- rpmsg virtio --> [ap] <-- rpmsg virtio --> [audio]

Add Rpmsg-Port-SPI transport layer.
Rpmsg Port SPI is a new rpmsg transport layer based on the Rpmsg Port,

1. Some platforms do not support interrupt mode (PCI_MSI/MSIX),
so add polling mode support, so these platforms can also use virtio-pci;
2. In some cases, we do not want to use the interrupt for virtio driver
to avoid time jitter, so add the polling mode support;
3. If CONFIG_DRIVERS_VIRTIO_PCI_POLLING_PERIOD <= 0, interrupt mode.
if CONFIG_DRIVERS_VIRTIO_PCI_POLLING_PERIOD > 0, polling mode.

Rpmsg VirtIO is a virtio transport implementation for Rpmsg, and
it's different to the rptun framework.
rpmsg_virtio.c implements the rpmsg virtio transport layer by itself
to avoid use the remoteproc implementation in OpenAMP to save code
size, so it can be treated as a lightweight version of rptun.
Therefore, rpmsg_virtio.c only support the communication feature and
do not support contoll the life cycle of the remote core.
But benefit by it's small footprint, it can be used in the chips with
small flash.
