If the raw PM support is built in, we are operating in the split

case, skip the board config for these two.

IMHO, using CONFIG_CLK_TI_SCI is hack here. Can we showhow derive this
information based on the images loaded in FIT?
At this point we have only loaded the sysfw image. DM image against which we
This sysfw.itb contains all the board configurations?
If yes, then we are adding board configurations in sysfw.itb that does not
belong here.
If no, then can we check for the entries before loading?
Technically feasible yes, let me check with Dave offline what we can
craft for this (the image generation part was done by him); the firmware
image generator does something along these lines already, basically
splitting the cfg portions to different images.

could check this will only be loaded during A72 SPL FIT loading process, and it
will only happen later.
