Update a couple of media drivers to the new IRQ API.

Some stuff in there doesn't link btw:

drivers/built-in.o: In function `rds_waitread':
drivers/built-in.o(.text+0x6c152): undefined reference to `aci_port'
drivers/built-in.o: In function `rds_rawwrite':
drivers/built-in.o(.text+0x6c1a3): undefined reference to `aci_port'
