    mtd: fsmc: Move ALE, CLE defines to their respective platform
    
    Address Latch Enable (ALE) and Command Latch Enable (CLE) defines are
    platform specific and were wrongly put in driver specific fsmc.h file.
    Move such defines to their respective platform.
    
    Also instead of relying on fsmc driver, pass ALE, CLE offsets explicitly
    from individual platform.
