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.

Using the ts/tick conversion functions provided in clock.h
Do this caused we want speed up the time calculation, so change:
clock_time2ticks, clock_ticks2time, clock_timespec_add,
clock_timespec_compare, clock_timespec_subtract... to MACRO

Add new driver frameworks: force feedback for vibrator, like linux,
unify vendor vibrator driver using.
Incorporating a force feedback-based driving framework to replace the
conventional driver/motor setup for controlling vibrators not only
enhances the precision and responsiveness of the haptic feedback but
also aligns better with the advancements in Linux-based driver systems.

1. Should check the vmid in ivshmem_remove() when release irq instead
check the ivdev->reg;
2. Add vmid check in ivshmem_probe() because ivshmem driver only support
vmid == 0 or 1 for now in NuttX;

Rptun is a rptun fremework driver base on the Inter-Virtual Machine
Share Memory Device.
With this driver, two NuttX runs in different QEMU can communicate
with each other by the rpmsg api.

Not consider the ops called in thread and intterupt simultaneously.

because if priv->rx_length is zero , need to call SPIS_CTRLR_QPOLL to
receive new data from lower half and update priv->rx_length.
This reverts commit 6cb649ecf6.
Basic amg88xx sensor handling (open, close, read, ioctl).
No interrupts supported. I intend to add support for this feature when I
gain more know-how on nuttx/posix.
