Subject: [PATCH] dmapool: Declare struct device

dmapool uses struct device in function arguments but relies on an implicit
inclusion to declare struct device causing warnings in some configurations:

include/linux/dmapool.h:31:7: warning: 'struct device' declared inside parameter list

Fix this by adding a struct device declaration to the file.
