    tegra132: Add code to setup chip operations and mem resources.
    
    With this memory resource, the payload loading code should be
    able to create a bounce buffer and load the payload successfully.
    
    Adapted from tegra124 soc.c
    
    BUG=None
    BRANCH=None
    TEST=Built and booted to ramstage on rush.
