The major difference between monaco-evk and monaco-ac-evk boards is that
of power grid. monaco-evk requires 4 PMICs (2x PM8650AU + Maxim MAX20018
+ TI TPS6594) to support higher power requirements of monaco-AA variant
of SoC which supports upto 40 TOPS of NPU - whereas this board
"monaco-ac-evk" supports 20 TOPS of NPU and has lesser power
requirements hence 2 PMICs suffice the power requirements (2x PM8650AU).

Ack, will change this to "monaco-ac-evk" in the next version.

Also, should I change DT name "monaco-ac-sku.dts" instead of current
"monaco-evk-ac-sku" ?
