Yeah, I know. PCI-DMA-mapping.txt says:

NOTE: DO NOT put a semicolon at the end of the DECLARE_*() macro.


But there are some other DECLARE_ macros that don't have the
semicolons so users could be easily confused.

#define DEFINE_DMA_MAP_ADDR(ADDR_NAME) dma_addr_t ADDR_NAME

looks better?

I plan to replace these PCI API with the new generic API so I can take
care of them together.
