Due to the wild nature of the Qualcomm RPM Message RAM, we can't really
use 'reg' to point to the MPM's slice of Message RAM without cutting into
an already-defined RPM MSG RAM node used for GLINK and SMEM.
Document passing the register space as a slice of SRAM through the
qcom,rpm-msg-ram property. This also makes 'reg' no longer required.
