Add Operation State Manager (OSM) L3 interconnect provider binding for
QCS615 SoC. As the OSM hardware in QCS615 and SM8150 are same,
added a family-level compatible for SM8150 SoC.

Add Operation State Manager (OSM) L3 interconnect provide node and OPP
tables required to scale DDR and L3 per freq-domain on QCS615 SoC.
As QCS615 and SM8150 SoCs have same OSM hardware, added SM8150
compatible as fallback for QCS615 OSM device node.
