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.

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.
In some usage scenarios, read and write tasks will be performed during interruptions. If sleep is used at this time, it will cause a timeout crash. Therefore, a macro is added to determine whether it is currently interrupted to select sleep/delay.

(SJA1000_FDTOL), "releasing" the buffer when the Rx buffer is empty

On peripheral initialise, remove the flag to "release" the buffer.
This should be safe for all systems using the SJA1000 CAN controller
as a "reset" to the peripheral clears the Rx FIFO.
