commit ace805e885a558b070b535ea9471daabe5635fbd

device: Add scan_generic_bus support

scan_smbus routine does not perform any smbus specific operation. Thus,
    rename the routine to scan_generic_bus so that it can be used by other
    buses like SPI. Add a wrapper scan_smbus to allow other users of smbus
    scan to continue working as before.
