    lantiq: backport kernel patch to pass of node to nand_dt_init
    
    Backport upstream commit a61ae81a1907af1987ad4c77300508327bc48b23.
    
    The actually purpose of the patch was to do some cleanup. As a side
    effect of this cleanup, the device node is now passed to nand_dt_init.
    
    This allows to use the common nand device tree properties
    
     - nand-bus-width
     - nand-on-flash-bbt
     - nand-ecc-mode
     - nand-ecc-step-size
     - nand-ecc-strength
    
    for the plat_nand driver.
