[PATCH v1 0/5] Support more sample rates, let the rates normal work

[Caesar Wang <wxt@rock-chips.com>]

That's seem the moment rockchip-codec driver other than 44100 and 48000 do not work.
Says the (max98090, rt5640).

----
As the chromeos reported issue:(https://chromium.googlesource.com/chromiumos/third_party/kernel/+/v3.14)

For detail:
In that bug we want to add 32000 to sound/soc/rockchip/rockchip_max98090.c rk_aif1_hw_params. However that does not work.

Previously, in https://chromium-review.googlesource.com/#/c/268398/ , rate 8000, 1600, 96000 were added.
However, those rates do not work. I got the same audio as 48000 when I run

aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 8000 -f S16_LE -c2
aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 16000 -f S16_LE -c2
aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 96000 -f S16_LE -c2

They all sound identical to
aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 48000 -f S16_LE -c2

Also, recording using
aplay -D hw:0,0 /usr/local/test.raw --rate 96000 -f S16_LE -c2  and examine the output we see it was recording using 48000.

Okay, let's add this series patchs to fix this issue.

arecord -D hw:0 -f S16_LE -c 2 --rate 96000 -d 5 foobar.wav
and
    aplay -D hw:0 foobar.wav
Tested on veyron devices.


Changes in v1:
- change the subject and commit.
- remove the print message dev_dbg().
- Fix a subject missspell.
