ALSA: pcm - fix page conversion on non-coherent PPC arch
The non-cohernet PPC arch doesn't give the correct address by a simple
virt_to_page() for pages allocated via dma_alloc_coherent().
This patch adds a hack to fix the conversion similarly like MIPS.
Note that this doesn't fix perfectly: the pages should be marked with
proper pgprot value. This will be done in a future implementation like
the conversion to dma_mmap_coherent().
