It looks like you were close to answering your own question. The file altera_avalon_dma.h is missing the line:

# include "sys/alt_dev.h"

if you add that in, the error will go away.

Alternatively, you will find that this problem will also disapear if you include either a JTAG_UART or UART in your design (since these drivers will include the missing header for you).
