David Rientjes 586f83e2b4 pnp: only assign IORESOURCE_DMA if CONFIG_ISA_DMA_API is enabled
IORESOURCE_DMA cannot be assigned without utilizing the interface
provided by CONFIG_ISA_DMA_API, specifically request_dma() and
free_dma().  Thus, there's a strict dependency on the config option and
limits IORESOURCE_DMA only to architectures that support ISA-style DMA.

ia64 is not one of those architectures, so pnp_check_dma() no longer
needs to be special-cased for that architecture.

pnp_assign_resources() will now return -EINVAL if IORESOURCE_DMA is
attempted on such a kernel.
