FROMLIST: arm64: dts: qcom: monaco: Add monaco-ac EVK board

Add initial device tree support for monaco-ac EVK board, based
on Qualcomm's monaco-ac (QCS8300-AC) variant SoC.

Compared to the existing monaco-evk board, which is based on the
QCS8300-AA SKU and uses a four-PMIC power delivery network
(2x PM8650AU, Maxim MAX20018, TI TPS6594) to support higher power
requirements, the monaco-ac EVK uses QCS8300-AC SKU
(with 20 TOPS NPU capability) and a simplified two-PMIC power
delivery network (2x PM8650AU).

Apart from the SoC SKU and PDN differences, the board layout and
peripherals are equivalent to the monaco-evk design and are reused
accordingly.
