Current rsnd driver updates pointer when DMA transfer was finished
in DMA transfer mode. But PulseAudio requests more accurate
pointer update when timer mode.
This patch consider about DMA transfer residue and update more
accurate pointer.

OF-graph base DT binding is used on V4L2, and ALSA SoC is using
different style of DT today. Now ALSA SoC supports simple-card driver
for generic/simple sound card, and we have simple-scu-card driver
for simple-card + ALSA DPCM case.
In the future, V4L2 / ALSA will support HDMI, and then, DT bindings
between V4L2 / ALSA should be merged.
This patch adds new Audio Graph SCU Card which is OF-graph base of

ALSA SoC needs to know connected DAI ID for detecting.
It is not a big problem if device/driver was only for sound,
but getting DAI ID will be difficult if device includes both
Video/Sound, like HDMI.
To solve this issue, this patch adds new snd_soc_get_dai_id() and
its related .of_xlate_dai_id callback on component driver.
In below case, we can handle Sound port (= port@2) as ID = 0
if .of_xlate_dai_id has its support.
hdmi {
port@0 { /* VIDEO */ };
port@1 { /* VIDEO */ };
port@2 { /* SOUND */ };
};
