Subject: [PATCH v2 3/4] parisc: Provide default implementation for dma_{alloc,free}_attrs

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

Add default implementations for these functions on parisc.
