Subject: Move isa_dma_bridge_buggy to generic location

Hi,

Microblaze misses isa_dma_bridge_buggy and I can easily add it but I 
think that we should move isa_dma_bridge_buggy to generic location. What 
is the correct location?

This is what all archs have in headers.

#ifdef CONFIG_PCI
extern int isa_dma_bridge_buggy;
#else
#define isa_dma_bridge_buggy 	(0)
#endif

Below is just grep where isa_dma_bridge_buggy is.

Thanks,
Michal
