[PATCH v2 1/2] remoteproc: imx_rproc: allow tx_block to be set

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Current tx_block is set to true, but there is case that no need to wait
response. Linux just needs to send data to remote processor, so let's
allow tx_block could be set to false. No functional changes.
