board: phytec: phycore-am62x: Use memory nodes in higher boot stages

There is no need to reread the EEPROM multiple times in different stages
to detect the RAM size. We can do this once at an early stage and let
higher stages decode memory nodes using fdtdec.
Make sure to pass fixup memory nodes before passing to u-boot stage.
