remoteproc: imx_rproc: Allow setting of the mailbox transmit mode
Current mailbox is blocking by default, but there are cases where we don't
need to wait for a response.
Linux just needs to send data to the remote processor, so let's
allow tx_block mode to be set (true/false) depending on usecase.
No functional changes.
