Subject: [PATCH v4 4/5] arm64: dts: qcom: qcs404: Add IMEM and PIL info region

Add a simple-mfd representing IMEM on QCS404 and define the PIL
relocation info region, so that post mortem tools will be able to locate
the loaded remoteprocs.

Signed-off-by: Bjorn Andersson <bjorn.andersson@...aro.org>
