[PATCH V5 4/8] remoteproc: imx_rproc: parse fsl,auto-boot

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

Parse fsl,auto-boot to indicate whether need remoteproc framework
auto boot or not.

When remote processor is booted before Linux Kernel up, do not parse
fsl,auto-boot, so only need to parse the property when rproc state is
RPROC_DETACHED.
