    mpc85xx: Get rid of 'of_flat_dt_is_compatible'
    
    This patch replaces 'of_flat_dt_is_compatible' with 'of_machine_is_compatible'.
    The TL-WDR4900 platform file won't compile in the 6.1 kernel. The platform
    files for the rest of the routers have been reworked or based on newer
    solutions.
    
    Let's make the TL-WDR4900 consistent with them.
