[RFC/PATCH 3/4] parisc: Provide default implementation for dma_{alloc,free}_attrs

[RFC/PATCH 3/4] parisc: Provide default implementation for dma_{alloc,free}_attrs

[Damian Hobson-Garcia]

Most architectures that define CONFIG_HAVE_DMA, have implementations for
both dma_alloc_attrs() and dma_free_attrs().  All achitectures that do
not define CONFIG_HAVE_DMA also have both of these definitions provided by
dma-mapping-broken.h.

Add default implementations for these functions on parisc.

Thanks!
Queued up in the parisc tree for 3.10
