Since commit 38cbf959
("ASoC: core: Try to use regmap if the driver doesn't set up any I/O")
any ASoC codec which doesn't set codec::control_data is assumed
to use regmap.  That doesn't work with AC97 so this workaround
sets the codec::control_data member to a random value to restore
proper behaviour.

Tested with WM9712.

There's a driver bug that sgtl5000 dapm widget kcontrols do not work.
e.g. can not select capture mux with amixer tool(no error info prompted).

The root cause is that we still call snd_soc_dapm_new_widgets in
codec driver probe function afer converting to table based widgets.
This will cause the card dapm widgets are instantiated before the
dapm_routes are registered.
Then, no available dapm widget pathes can be found during instantiation
which finally will cause soc_dapm_mux_update_power to fail(can not find
correct path with kcontrol) in snd_soc_dapm_put_enum_double function.

Here we remove the unneeded snd_soc_dapm_new_widgets in codec probe
and let the soc core to handle the register sequence properly.
Then we can fix above issue.

In sound/soc/codecs/tlv320aic3x.c

        data = snd_soc_read(codec, AIC3X_PLL_PROGA_REG);
        snd_soc_write(codec, AIC3X_PLL_PROGA_REG,
                      data | (pll_p << PLLP_SHIFT));

In the above code, pll-p value is OR'ed with previous value without
clearing it. Bug is not seen if pll-p value doesn't change across
Sampling frequency.

However on some platforms (like AM335x EVM-SK), pll-p may have different
values across different sampling frequencies. In such case, above code
configures the pll with a wrong value.
Because of this bug, when a audio stream is played with pll value
different from previous stream, audio is heard as differently(like its
stretched).
