commit 8fbe22e701ef6cf6caae40c42e2550d66a083f85
Author: Kyösti Mälkki <kyosti.malkki at gmail.com>

    Add macros for component paths
    
    __CHIP_PREFIX__ expands to the component path, like
       southbridge_intel_i82801gx_
    
    The prefix is used for DEVICE_NAME and ROOT_COMPLEX_NAME to assign
    the device name in a follow-up patch. It should be used in a similar
    fashion for struct chip_operations.
