ALSA: hda: Remove page allocation redirection
The HD-audio core allocates and releases pages via driver's specific dma_alloc_pages and dma_free_pages ops defined in bus->io_ops. This was because some platforms require the uncached pages and the handling of page flags had to be done locally in the driver code. Since the recent change in ALSA core memory allocator, we can simply pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only difference became about this type to be passed to the core allocator. That is, it's good time for cleaning up the mess. This patch changes the allocation code in HD-audio core to call the core allocator directly so that we get rid of dma_alloc_pages and dma_free_pages io_ops. If a driver needs the uncached pages, it has to set bus->dma_type right after the bus initialization. This is merely a code refactoring and shouldn't bring any behavior changes.
