Subject: [PATCH v3] arm64: dts: qcom: sm8450: Add IMEM and PIL info region
Add a simple-mfd representing IMEM on SM8450 and define the PIL
relocation info region, so that post mortem tools will be able
to locate the loaded remoteprocs.
Signed-off-by: Mukesh Ojha <quic_mojha@...cinc.com>

Change in v3:
- Sorted by address.
Changes in v2:
- put ranges after regs and corrected the sram node position.
