    The ltpc driver is rather outdated and does not get built on most
    platforms because it requires the ISA_DMA_API symbol. However
    there are some ARM platforms that have ISA_DMA_API but no virt_to_bus,
    and they get this build error when enabling the ltpc driver.
    
    drivers/net/appletalk/ltpc.c: In function 'handlefc':
    drivers/net/appletalk/ltpc.c:380:2: error: implicit declaration of function 'virt_to_bus' [-Werror=implicit-function-declaration]
      set_dma_addr(dma,virt_to_bus(ltdmacbuf));
      ^
    
    This adds another dependency in Kconfig to avoid that configuration.
