accel/amdxdna: Support hardware mailbox
The hardware mailboxes are used by the driver to submit requests to
firmware and receive the completion notices from hardware.
Initially, a management mailbox channel is up and running. The driver may
request firmware to create/destroy more channels dynamically through
management channel.
Add driver internal mailbox interfaces.
- create/destroy a mailbox channel instance
- send a message to the firmware through a specific channel
- wait for a notification from the specific channel
