While the patchset [1] supports SA8255P as a standalone SoC, this series
offers an alternative by introducing SA8255P as a Lemans family SoC.

Lemans family includes IOT SoCs IQ-9 and AUTO SoCs SA8775P, SA8255P.
Among them, IQ-9 and SA8775P have platform resources clocks, regulators,
interconnects etc, managed in HLOS, while SA8255P has them configured in
firmware via SCMI.  All Lemans family SoCs actually share the same
hardware configurations like memory maps, interrupts, DMAs, etc.

This patchset moves those platform resources out of lemans.dtsi and get
them accommodated in lemans-iq9.dtsi, so that lemans.dtsi can cover
SA8255P as well, like lemans-sa8255p.dtsi includes lemans.dtsi and
overrides/adds properties as needed.
