Add RPM Glink, RPM message RAM and SMPA1 regulator
nodes to support frequency scaling on IPQ9574
Signed-off-by: Devi Priya <quic_devipriy@xxxxxxxxxxx>

Changes in V2:
- Splitted the RPM and CPU Freq changes to individual patches
- Moved the regulators node to Board DT
- Dropped the regulator-always-on property
- Updated the compatible in regulators node with the existing
mp5496 compatible

This belongs in a separate patch.
Do you recommend to move this change to the below patch in the next spin?

Since this is a part of the MMIO region and not a part of DRAM,
we generally put this node under /soc with the compatible of
qcom,rpm-msg-ram and without no-map.
And the node name then should be sram@.
Sure, okay. Will update this in V3
