No, this is not true. On QCM2290 the modem DSP is being used to download
wlan firmware. As such this is wrong.

[ 4.186507] remoteproc remoteproc0: modem is available
[ 14.811564] remoteproc remoteproc0: powering up modem
[ 14.883766] remoteproc remoteproc0: Booting fw image qcom/qcm2290/modem.mbn, size 8881672
[ 15.505182] remoteproc remoteproc0: remote processor modem is now up
