soc/amd/picasso: add devicetree setting for PSPP policy
Since the default for the corresponding UPD of the Picasso FSP is
DXIO_PSPP_POWERSAVE and the devicetree default is DXIO_PSPP_PERFORMANCE,
add a deviectree setting for each board that's using the Picasso SoC
code to not change the setting for the existing boards.
