[PATCH V2] remoteproc: imx_rproc: Ignore create mem entry for resource table

[PATCH V2] remoteproc: imx_rproc: Ignore create mem entry for resource table

[Peng Fan (OSS)]

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

Resource table will not be used for memory allocation, no need to create
rproc mem entry.

Fixes: b29b4249f8f0c ("remoteproc: imx_rproc: add i.MX specific parse fw hook")
