octeontx2-af: Add mailbox IRQ and msg handlers
This patch adds support for mailbox interrupt and message
handling. Mapped mailbox region and registered a workqueue
for message handling. Enabled mailbox IRQ of RVU PFs
and registered a interrupt handler. When IRQ is triggered
work is added to the mbox workqueue for msgs to get processed.
