[PATCH v6] arm64: dts: qcom: sdm845: Add Q6V5 MSS node

[Sibi Sankar]

This patch adds Q6V5 MSS remoteproc node for SDM845 SoCs.

v6:
  * Drop unused mbox-names property
  * Add mss_pil label
  * Rebased to Andy's for-next

v5:
  * Use qmp_aop updated dt binding

v3:
  * with shutdown-ack irq redesign make it mandatory,
    merge multiple patches into a single one

v2:
  * Fixed style changes
  * Added missing clocks in the dt-bindings
  * Split mss remoteproc node into a number of patches

This patch depends on the following bindings:
https://patchwork.kernel.org/patch/10662089/ - mba/mpss reserved regions
https://patchwork.kernel.org/patch/10657325/ - pdc reset node
https://patchwork.kernel.org/patch/10755191/ - rpmhpd dt node
https://patchwork.kernel.org/patch/10755197/ - rpmhpd dt binding
https://patchwork.kernel.org/patch/10749469/ - AOP QMP dt binding
https://patchwork.kernel.org/patch/10751757/ - shutdown-irq binding

This will now need to be adjusted to:

reg = <0 0x04080000 0 0x408>, <0 0x04180000 0 0x48>;

This fixes things up to deal with the patch ("arm64: dts: qcom:
sdm845: Increase address and size cells for soc"), AKA:
- https://patchwork.kernel.org/patch/10767511/
- https://lkml.kernel.org/r/20190117042940.25487-2-bjorn.andersson@linaro.org

Yup, this was on my todo list after Bjorn
posted out the patch
