net/appletalk: LTPC needs virt_to_bus
The ltpc driver is rather outdated and does not get built on most platforms because it requires the ISA_DMA_API symbol.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.

This allows you to use the AppleTalk PC card to connect to LocalTalk
networks. The card is also known as the Farallon PhoneNet PC card.
