[PATCH 1/2] remoteproc: qcom_q6v5_mss: Populate additional devices from DT

[Stephan Gerhold <stephan@gerhold.net>]

Some devices without own memory resources could be placed anywhere in the
device tree but they logically belong to the modem remote processor. Make
it possible to probe them when defined under the mpss device tree node
by calling of_platform_populate().

This can be used for BAM-DMUX for example, which provides the WWAN network
interfaces on some older Qualcomm SoCs such as MSM8916 or MSM8974.
