[v2] arm64: dts: qcom: sdm660: Add initial IFC6560 board

The IFC6560 is a board from Inforce Computing, built around the SDA660
SoC. This patch describes core clocks, some regulators from the two
PMICs, debug uart, storage, bluetooth and audio DSP remoteproc.

The regulator settings are inherited from prior work by Konrad Dybcio
and AngeloGioacchino Del Regno.

Changes since v1:
- Fixed typo 29p5 -> 2p95 in two regulators.

This is already defined in sdm630.dtsi.

No voltage range?

That's not Nile/Ganges ;)

Please validate whether this voltage mess also concerns your board.

That's identical to blsp1_uart2_default from sdm630.dtsi. While I agree

hardcoding pinctrl-names to "default" is a good idea, should a sleep state

be added to the SoC DTSI (so that it doesn't get passed in here unvalidated),

I don't think you need to redefine this one.
