Considering yours and other comment about the DT describes the hardware,
the only common thing between these boards will be memory map in
qcm6490.dtsi and at this moment it does not seem fine to have
qcm6490.dtsi just for memory map however, we can always comeback in the
future if there are more other common things between these IOT family
platforms.

PMIC_GLINK.
Currently there is no support for glink for this soc, that's why
going ahead with peripheral mode.
