Check the continuity of allocated pages to reduce the BDL size as much
as possible so that it can use more than 1MB buffers.

Most hardwares have limited buffer-descriptor table length. This
also restricts the max buffer size of the sound driver.
For example, snd-hda-intel has 1MB buffer size limit, and this is
because it can have at most 256 BDL entries. For supporting larger
buffers, we need to allocate larger pages even for sg-buffers.
This patch changes the sgbuf allocation code to try to allocate
larger pages first. At each head of the allocated pages, the
number of allocated pages is stored in the lowest bits of the
corresponding entry of the table addr field. This change isn't
visible as long as the driver uses snd_sgbuf_get_addr() helper.
Also, the patch adds a new function, snd_pcm_sgbuf_get_chunk_size().
This returns the size of the chunk on continuous pages starting at
the given position offset. If the chunk reaches to a non-continuous
page, it returns the size to the boundary.

snd_dma_alloc_pages_fallback() always tries to reduce the size in a half,
but it's not good when the given size isn't a power-of-two.
Check it first then try to align.

The SPDIF output is toggled at each time any SPDIF status bits are changed
because of the known problems on some codecs. But, this also results in
loosing the sync, and the problem is more obvious on HDMI output over
SPDIF. Since the toggle is necessary only for some codecs, we should
check whether this workaround is needed and skip if unnecessary.
