Is there a way we can estimate how much power our final PCB would need? Can we find out how much power the SoC itself uses (without all the EVM stuff around?)
Yes,
according to the EVM Reference Guide (swcu130) secion 4.2 there are some 30 mOhm 0.5% resistors on the board so that we can measure the current at several places individually.
Another idea is to break into U-Boot console and measure then. Most certainly it is running in single core low clock (300 MHz?) mode.
If I remember correctly my first experiment the whole EVM did draw ~400mA at 5V.
