Subject: [PATCH] LF-4484: remoteproc: imx-dsp-rproc: Avoid power on device
after probe
With multiple power domain case, don't need to use flag
DL_FLAG_RPM_ACTIVE when device linking, otherwise the power
is always enabled after probe.
With DSP's case, the power may increase about 20% for whole system
when DSP is enabled wrongly.
Fixes: d2634e10d191 ("LF-4209-1: remoteproc: imx_dsp_rproc: add remoteproc driver for dsp")
