init dma masks in pnp_dev
PNP now initializes device dma masks, which prevents oopses when generic dma calls are made using pnp device nodes. This assumes PNP only uses ISA DMA, with 24 bit addresses; and that it's safe to init those masks for all devices (rather than finding out which devices have been assigned DMA channels, and handling only those).
