media: amphion: implement vpu core communication based on mailbox
driver use mailbox to communicate with vpu core.
and there are a command buffer and a message buffer.
driver will write commands to the command buffer,
then trigger a vpu core interrupt
vpu core will write messages to the message buffer,
then trigger a cpu interrupt.
